Delivery & Product Management

Renaud Roustang

Manager of the Delivery & Product Management Practice, Renaud Roustang supports organizations in the success of their strategic and transformation projects (Data, AI, IT). Starting from your challenges and your context, he designs a tailored response by identifying key skills and the appropriate delivery model. His commitment: structuring governance to secure deliverables and turn your ambitions into sustainable performance.

Nexans, a global industrial leader (15,000 employees, >€6B revenue), places sustainable transformation at the heart of its value creation strategy through its E3 model (Economy, Engagement, Environment). Faced with the growing complexity of European Taxonomy requirements and the CSRD directive, the group encountered an imperative: structuring an extra-financial data chain offering a level of rigor, auditability, and reliability traditionally reserved for financial data.

To address this challenge and steer this strategic transformation, Nexans relied on MARGO. Acting as a technology consulting and delivery partner, MARGO orchestrated the insourcing of the reporting system and deployed a unified data platform, natively embedding sustainability into the group’s overall business performance.

Strategic Indicator	Result Obtained
Compliance & Auditability	100% guaranteed alignment (European Taxonomy, CSRD) with validation of Traceable Audit Trails (PAT) by statutory auditors.
Time-to-Market	Accelerated delivery in 5 months with a commitment to results on the platform deployment.
Financial Performance	€120k in annual savings secured from production launch thanks to the termination of outsourcing services.
Governance & Sovereignty	100% autonomy transferred to internal teams, regaining absolute control over their data and calculation engines.

The Challenge: Mastering Regulatory Risk and Restoring Data Sovereignty

Like financial institutions subject to SFDR directives, major industrial groups indeed face a regulatory wall demanding impeccable management of their data assets. Initially, Nexans relied on a manual environmental reporting process outsourced to a third party.

This outsourced architecture exposed the organization to three major systemic risks:

A risk of non-compliance and opacity: inability to instantly provide the Traceable Audit Trails (PAT) required by external auditors.
Operational inertia: rigidity of calculation engines in the face of rapidly evolving European directives.
Value attrition: recurring operating costs without building a sustainable internal technological asset.

Faced with these constraints, Nexans’ Sustainability & Corporate Transformation department needed to closely align Business, Finance, and IT functions to insource this critical chain. Consequently, the challenge went beyond mere compliance: it was about designing a governed infrastructure capable of consolidating heterogeneous data distributed globally while creating a sustainably valuable technological foundation.

The MARGO Solution: Sovereign Data Platform, Governance, and AI-Readiness

It is precisely to address this dual challenge of compliance and performance that MARGO designed and executed a tailored cloud architecture. The solution is based on a multi-source Data Platform combined with a configurable calculation engine, offering total control to CSR and Finance departments.

To ensure the longevity of this foundation, this architecture deploys the most advanced engineering standards:

Distributed computing and scaling: business rules modeling via Python and high multi-source volume processing with Azure Databricks.
AI-Ready Foundation and Governance: strict standardization of ESG flows creates a healthy and auditable data foundation. This architectural prerequisite is essential to envisage future advanced use cases (predictive carbon footprint modeling, integration of generative AI agents for document querying) without rebuilding the infrastructure.
Persistence and business accessibility: deployment of an intuitive React application for operational staff, backed by the power of Cosmos DB.
Industrialization (CI/CD): deployment automation using Infrastructure as Code (IaC) via Azure DevOps, ensuring bank-grade robustness in production.

Execution Excellence: Securing Delivery in Critical Environments

Beyond the technical solution, leading complex data projects under tight regulatory constraints demands an executive methodology combining velocity with strict risk management. The success of this transformation rests on three operational pillars:

1. Commitment to Results

The project was structured as an accelerated fixed-price Delivery over a strict 5-month window. This model provides executive management with total visibility: budget control, strict milestone compliance, and assumed responsibility for deliverable quality.

2. Strict RACI & Governance

The integration of a MARGO Delivery Manager working closely with Nexans decision-makers helped establish seamless governance. MARGO technology squads and Nexans experts operated within a rigorous RACI matrix to unblock obstacles and secure decisions.

3. Data Quality “by design”

The architecture natively integrates automated validation mechanisms within each data pipeline. This certified integrity across the entire chain guarantees the accuracy of sales alignment reports during external audits.

In these critical transformation projects, trust is built on rigor of execution. MARGO established itself as a strategic partner, combining technological excellence and delivery mastery to guarantee the compliance and sustainability of our ESG platform. David Grall, Vice-President Sustainability & Corporate Transformation, Nexans

Replicable Expertise for Highly Regulated Sectors

Building on these results, the engineering deployed for Nexans demonstrates MARGO’s proven ability to secure critical data architectures well beyond industry:

Sustainable Finance & Insurance (SFDR, NFRD, BCBS, Solvency II): design of auditable calculation engines for portfolio alignment and prudential risk reporting.
Industry & Energy: structuring complex international data flows while maintaining legacy system interoperability.
Sovereignty & Cybersecurity: deployment of sovereign Cloud architectures (IaC) complying with the strictest security standards (SecNumCloud, DORA).

Partner in Your Technological Transformation

Turn Your Regulatory Constraints into Performance Drivers

Ultimately, insourcing a heavy regulatory process proves to be a powerful driver of operational excellence. By combining strategic vision with execution rigor, Nexans turned a European constraint into a sovereign data platform ready for future technological challenges.

Secure your critical Data architectures and entrust the delivery of your strategic projects to MARGO’s expertise.

How to Accelerate Your IT Delivery in the Face of High Technological Complexity with MARGO Premium Nearshore

Emma Santimone — Thu, 11 Jun 2026 08:58:40 +0000

Head of MARGO Polska

Alexandre Le Mée

A results-oriented leader with a strong entrepreneurial spirit, Alexandre currently leads MARGO Poland, bringing a decade of successful experience in business development within the Polish market.

In a technological market where innovation dictates the pace, execution at scale becomes a critical issue for global leaders. Criteo, a major player in retail media and digital marketing on a global level, operates within a highly multicultural and international ecosystem. Their technological environments are extremely demanding and resolutely oriented towards real-time data and platforms.

This infrastructure also integrates a strong dimension linked to artificial intelligence, thereby imposing colossal challenges in terms of performance, reliability, and scalability. To support this dynamic of constant transformation and automate its industrial data flows, Criteo made the strategic choice to partner with MARGO.

The challenge: maintaining software engineering excellence at a large scale

The very nature of Criteo’s business is to be fundamentally focused on perpetual technological transformation. Faced with an ultra-dynamic and increasingly competitive market, the company must continuously evolve its offering and massively automate its data flows. However, maintaining very high engineering standards at a large scale requires highly specialized expertise, combining technical excellence, a fine understanding of the product, and business requirements.

Criteo already had an outsourcing model in India. However, to respond to its new transformation challenges, the company wished to rely on additional efficiency relays on the nearshore side. The objective was to complement this offshore setup in order to improve overall competitiveness and scale the technological organization.

The solution: Nearshore Premium, a true driver of strategic engineering

The MARGO Polska hub or the requirement for tailor-made technology

To meet these requirements without any compromise, MARGO deployed its technological excellence hub. MARGO Polska is a strategic pillar of the group, entirely dedicated to strong expertise such as architecture, data engineering, Cloud, AI, and advanced software development.

Far from low-cost outsourcing logic, we operate a Nearshore Premium model. This setup is meticulously designed to offer you the delivery quality and fluid execution of a local (onshore) team, while bringing you the flexibility and economic efficiency characteristic of nearshore. As Alexandre Le Mée, Country Manager of MARGO Polska, points out, when projects gain in complexity, nearshore can no longer be reduced to a simple cost optimization logic. When it is structured and governed, it becomes a true driver of strategic engineering, capable of supporting projects with very high technological complexity.

The issue is not to export skills, but to fully integrate them into a unified governance. For Criteo, this translated into the integration of Polish talent who do not limit themselves to code execution. Our teams intervene across the entire value chain, from architecture to delivery, actively participating in product decisions. MARGO stands out for its ability to propose the right profiles, placing vital importance on « soft skills », which are essential for getting teams up to speed quickly on high-stakes projects.

A « Zero Friction » approach for smooth integration

The success of this integrated engineering model relies on total organizational coherence. The Warsaw consultants act as a natural extension of your teams. Thanks to an identical time zone, a shared European engineering culture, and perfect mastery of English, they integrate continuously using a « Zero Friction » approach. They directly use your tools, your methods, and your rituals to ensure collaboration without any interruption.

In the context of the Criteo project, distance is largely erased thanks to this geographical and cultural proximity. Coordination, regular exchanges, and frequent travel allow for a highly fluid collaboration with Parisian teams, all operating within a simple, legal, and highly secure administrative framework.

Focus: The Polish tech hub in figures

The choice of Poland to establish our Nearshore Premium hub is a highly strategic decision. Poland stands out as a leading software engineering hub in Europe. It is a growing technological powerhouse, with an IT market generating 31.6 billion dollars in revenue and a sector representing 4.5% of the national GDP.

This talent pool of new-generation engineers has more than 650,000 tech professionals and sees the arrival of 74,000 new ICT graduates each year. Technical excellence meets strong cultural maturity there: the country ranks 3rd in the HackerRank ranking of the best developers in the world and 15th in the EF English Proficiency Index ranking.

This unique positioning offers an undeniable economic efficiency, generating 25% to 40% savings compared to French onshore teams, while guaranteeing a strictly equivalent level of quality.

The results: IT delivery acceleration and sustainable competitiveness

The deployment of this integrated engineering currently brings tangible and structuring value to Criteo’s organization. The Polish model offers an excellent balance between sharp technical expertise, agile maturity, and cost competitiveness. This optimal balance between Offshore and Nearshore allows Criteo to achieve a very high level of performance while ensuring a strong alignment with its demanding technological model.

On a daily basis, MARGO’s Polish profiles integrate fully into Criteo’s teams and take part in critical projects with a high level of responsibility and autonomy. For Moncef Bouaita, Agile Delivery Lead at Criteo, the balance sheet of this technological partnership is clear: collaboration with MARGO made it possible to drastically accelerate delivery for Criteo, without ever imposing compromises either on the quality of deliverables or on the company’s engineering standards.

I unhesitatingly recommend MARGO’s Nearshore Premium model to any Information Systems Department (ISD) looking for excellence, reliability, and absolute commitment to strategic technological issues. Moncef Bouaita, Agile Delivery Lead at Criteo

Ensuring seamless technology integration and data architecture post-M&A For a leader in Retail Media

Emma Santimone — Wed, 10 Jun 2026 12:34:50 +0000

As part of the strategic acquisition of an American startup publishing a cutting-edge analytics platform, a global leader in advertising technologies and Retail Media called upon MARGO to master and integrate this critical data asset.

This platform, essential for retailers to steer the performance of their products, relied on a complex, poorly documented legacy architecture, initially maintained by a team of 40 engineers.

Intervening during a critical transition phase where headcount had already fallen to 20 people, MARGO deployed an elite engineering unit to ensure the reverse engineering of the system, guarantee absolute service continuity, and orchestrate the sunsetting strategy of the application. This intervention secured the intellectual property while drastically reducing the technical resources mobilized (from 40 to 3 engineers), thereby ensuring the technological success of this high-tension M&A integration.

Challenges: mastering a critical technological asset in a merger and acquisition context

During an acquisition, the target’s technical debt often represents a major risk. Following the buyout, the group imperatively needed to regain control of the target platform, a complex analytical engine blending advertising campaign data, massive web scraping, and delivery via dashboards.

The stakes went beyond mere maintenance in operational conditions. It was a matter of defusing a technological « black box » to avoid any impact on our client’s business:

Financial and image risk:

Prevent any loss of visibility for retailers on their performance KPIs.

Operational risk:

Secure the Sales teams’ ability to support their clients with reliable real-time data.

Continuous development:

Maintain velocity to develop new strategic features requested by clients.

Risk of Intellectual Property (IP) loss:

Capture the business knowledge of a system maintained by a departing American team.

Objective: a rescue mission and strategic transmission

The challenge for MARGO was not to indefinitely maintain an aging infrastructure, but to steer a true technological safeguarding operation during a pivotal phase. In this uncertain transition context, the mission transformed into a resilience challenge built around a critical triptych.

First, the absolute imperative was business continuity: guaranteeing « Zero Downtime » so that the platform buyout remained seamless and painless for end retailers.

Next, the challenge was human and operational: it was necessary to industrialize the impossible by enabling a commando team of 3 MARGO experts to absorb the workload and complexity previously managed by the initial team of 40 engineers.

Finally, the mission targeted the future. It was not just about « running » the system, but preparing its intelligent sunsetting. The objective was to transform a complex and undocumented legacy code into a structured knowledge base. By extracting calculation rules and data schemas, MARGO enabled the group’s internal teams to take over the torch and rebuild these strategic functionalities on their own technological standards, without loss of know-how.

Approach: industrialization, microservices and asynchronous agility

To achieve this maximum efficiency, the MARGO team replaced a manual approach with aggressive industrialization on the Google Cloud Platform (GCP) foundation.

Resilience through orchestration (Kubernetes): since large-scale scraping (a minimum of 2 million web pages scraped per day, covering products, categories, and keywords) is inherently unstable, MARGO leveraged Kubernetes to isolate each collection engine in ephemeral containers. In case a scraper failed, the infrastructure self-healed without human intervention, allowing a reduced team to manage massive flows.

Microservices architecture and asynchronous communication (GCP Pub/Sub): the architecture relied on decoupled microservices communicating via Google Cloud Pub/Sub. This model enabled high scalability, better resilience, and independent evolution of services despite headcount reductions.

FinOps and scalability (BigQuery): to absorb large variations in data volume inherent to migration phases, the architecture was oriented towards Serverless via BigQuery. This model guaranteed consistent performance for users on Looker Studio.

Asynchronous governance (Kanban): faced with the constraints of the time difference with the United States, MARGO established a strict Kanban framework, removing human bottlenecks and ensuring a smooth knowledge transfer.

Delivery: the 3 steps of a high-tension transition

MARGO’s intervention was not limited to simple maintenance; it followed a methodical execution narrative to transform a major risk into a documented success.

Step 1: immersion and risk mapping

From day one, the challenge was to absorb a complex architecture (Python, SQL, Angular, Django, PostgreSQL) in record time. This Flash Audit and Knowledge Transfer phase allowed for mapping functional risks and securing critical access, thereby creating a knowledge bridge between the outgoing American team and the MARGO crisis unit.

Step 2: industrialization at the service of the run

Once the platform was mastered, the team moved into the industrialization phase. The objective: stabilizing data pipelines via proactive monitoring and automating flow restarts. By becoming the guarantor of the data, MARGO ensured high-responsiveness support for the Sales teams, allowing client requests to be handled without any delay despite the massive reduction of the original technical team. It was during this phase that the scale capacity was proven, with the scraping of several million pages per day.

Step 3: sunsetting and heritage transmission

The mission concluded with a secured shutdown phase orchestrated alongside SRE teams. The achievement of this step lies in reverse engineering: the MARGO team formalized all processing workflows and business rules. By documenting every KPI and every flow, we guaranteed that the startup’s data heritage and intellectual property were fully preserved and ready to be reintegrated into our client’s proprietary solutions.

Results: a secured integration and multiplied efficiency

Strategic Indicator	Result Achieved	Business & M&A Impact
Service continuity	100% availability	Zero interruption in analytics for end retailers.
Resource efficiency	3 MARGO experts mobilized	Successful replacement of an initial team of 40 people.
Data capacity (scale)	> 2 million pages / day	Massive scraping (Product/Category/Keyword) without operational overhead.
Technological heritage	Full functional documentation	Transformation of technical debt into a documentary asset for product teams.

The MARGO team managed to take control of a complex platform very quickly and ensure its stability within a highly constrained post-acquisition context. Responsiveness to incidents and the rigor of their methodology were decisive assets. Group Engineering Manager

First Job as an Engineer: Technical Expertise Is Gained by Tackling Complex Problems

Emma Santimone — Tue, 12 May 2026 08:20:43 +0000

The choice of your first job determines the value of your technical signature for the decade to come. For a junior engineer, the challenge does not reside in finding a project, but in integrating an ecosystem capable of transforming academic potential into reference expertise. At MARGO, we apply a « Consultant First » philosophy: we believe your technical progression is the sole driver of our organic growth, which has been constant since 2005.

A « Consultant First » vision: where excellence is cultivated

Excellence is not an abstract concept; it is the result of a friction-free environment. For a recent graduate, the worry regarding a first job is often becoming a mere number within an anonymous structure. At MARGO, we overturn this paradigm.

Being “Consultant First” starts with an irreproachable working framework: health insurance and a Navigo pass covered at 100%, alongside offices on the 27th floor of the Aurore Tower, designed as an exchange hub rather than a simple transit space. Beyond comfort, it is the certainty that every project you work on has been selected for its architectural complexity. We assign you a project to respond to a challenge where your skill development is the key to success.

How the EXCELLENCE Hub works: mentorship by your peers

The biggest fear of a junior developer is technical stagnation or isolation at a client’s site. To address this, we created the MARGO EXCELLENCE Hub. Here, your manager is not a sales profile, but a Practice Manager. This is a senior technical expert who belongs to your community: Software Engineering, Cloud Transformation, Artificial Intelligence, Data, Capital Markets, or Insurance.

This peer management changes everything. Your Practice Manager understands your code challenges, your bottlenecks on Kubernetes, or your questions on optimizing a C++ algorithm. This tailor-made mentorship allows you to choose your technical battles. You are not constrained by a rigid project catalog; you build your path based on the stack you want to master. Whether you aim for ultra-low latency in capital markets or the industrialization of Computer Vision models, the EXCELLENCE Hub secures your progression through weekly follow-ups.

Unlimited skill development: investment proven by facts

The ambition of recent graduates is often held back by a lack of real investment from companies. At MARGO, technological excellence is an audited investment. In 2024, we delivered 726 technical coaching sessions. These are not off-the-shelf theoretical training modules, but Pair Programming sessions, rigorous code reviews, and architecture design workshops.

For a junior developer, this means benefiting from the experience of senior consultants who have already encountered large-scale production challenges. This dynamic, named The Endless Momentum, translates into firm commitments:

The guarantee of one certification per year: We fund and clear time for you to validate your skills on market standards (AWS Certified, CKA for Kubernetes, GCP or Azure certifications).
Learning Expeditions: Privileged moments of intensive technology monitoring to explore the new frontiers of generative AI or Cloud Native.
Software Craftsmanship: We do not compromise on quality. You learn and apply SOLID principles, TDD (Test Driven Development), and Clean Code from your very first project.
Community impact: We encourage you to stand out from the crowd. By becoming a speaker at our Meetups (such as the C++FRUG) or by writing articles for our expert blog, you develop your Personal Branding. You do not just work for MARGO; you build your own technical authority in the industry.

ONE MARGO: a united collective without borders

The ambition of a young engineer is often international. The ONE MARGO philosophy unifies our hubs in Paris, London, and Warsaw. We have harmonized our engineering standards: a developer in La Défense uses the same tools, the same rigor, and the same processes as a counterpart in London.

This architecture offers you total portability of your skills. It facilitates peer exchanges on a European scale and allows you to measure your working methods against the most demanding financial and technological marketplaces. You belong to a collective of 400 experts, a critical mass that enables both entrepreneurial agility and a major technological strike force.

An infrastructure designed for performance and the balance of a first job

Supporting such a career in IT engineering requires a healthy lifestyle that we actively back. Certified as a Great Place to Work® and ranked in the Best Workplaces 2026 list, MARGO rejects the idea that excellence must come at the expense of personal balance.

Team spirit is also cultivated outside of code. Our daily, fully covered Yoga, Running, and Football sessions are essential moments for decompression and cohesion.

Join MARGO as a springboard for your career

MARGO is not a traditional IT services company; it is a collective of engineers in organic growth since 2005. We look for unique talents, curious minds who are not satisfied with the status quo.

Securing High-Risk Production with Agent-Based AI in the Banking, Finance and Insurance Sector

Emma Santimone — Fri, 17 Apr 2026 08:02:53 +0000

Executive Summary

In the capital markets ecosystem, data is the engine, but punctuality is the rule. Within the Risk Department of a major Corporate and Investment Bank (CIB), producing risk metrics (VaR, Limits) is a critical mission processing 6 billion data points daily.

Faced with this explosion of complexity, MARGO integrated a pioneering AI expertise cell to transform manual supervision into a predictive and autonomous system. By deploying a cutting-edge multi-agent architecture, we secured the SLE (Service Level Expectation) while restoring value to the analysts’ work.

The Strategic Challenge: Overcoming the limits of human supervision

The infrastructure digitalization project took place in a “Scaling Law” context: the volume of data had become so large that manual tracking of calculation chains was structurally impossible to perform accurately.

Operational Risk: Any incident on the calculation chain starting at midnight threatens the delivery of indicators to regulators and traders.
The Bottleneck: Teams of experts were mobilized on repetitive support tasks at the expense of high-value risk analysis.
Cognitive Debt: A massive base of business procedures, difficult to mobilize instantly during critical nighttime incidents.

MARGO’s Objective: Shift from a reactive posture (crisis management) to a proactive posture (preventing failure).

The Solution: Hybrid Artificial Intelligence

MARGO designed a dual strategy, combining the statistical power of traditional Machine Learning with the reasoning capabilities of Generative AI.

Anticipation: The Predictive Monitoring Engine (PSM)

Using predictive maintenance models, this tool analyzes data flows in real-time from the very beginning of the cycle.

Innovation: It associates a probability of success with SLE compliance.
Impact: If a weak signal indicates a potential delay, operational teams are alerted before the anomaly becomes critical.

Autonomy: Intelligent Multi-Agent System

Based on LangChain and LangGraph, this system goes beyond a simple chatbot to become a true agentic “co-pilot.”

RAG Pattern (Retrieval-Augmented Generation): Instant access to all business documentation for ultra-fast diagnosis.
ReAct Pattern (Reasoning & Acting): The AI does not just respond; it reasons, identifies anomalies in logs, and suggests concrete resolution steps.

Methodology: Trustworthy AI (Human-in-the-loop)

For a highly regulated financial environment, AI cannot be a “black box.” MARGO implemented three pillars of trust:

Explainability:

Each decision made by the agent is justified by a logical reasoning step.

Sovereignty:

Humans remain in control of the final decision. AI facilitates the management of tedious tasks to allow experts to focus on complex issues.

Adoption:

Total immersion of MARGO consultants within production teams to ensure the tool meets real-world field constraints.

Business Impact & ROI

The implementation of MARGO’s solutions generates tangible benefits, transforming support into a performance lever.

Key Metric	Measured / Target Impact
SLE Reliability	Drastic reduction in production delays
Operational Efficiency	Easier chain monitoring for non-IT profiles, reducing ticket volume
HR Optimization	Redirection of 30 analysts toward high-value tasks
Diagnostic Time	66% efficiency gain (resolution time dropping from 3 days to 1 day on average)

MARGO’s approach allowed us to cross a major technological threshold. Agentic AI is no longer just a laboratory promise; it has become a concrete ally for our production teams on a daily basis. IT Risk Manager

Outlook: Toward Self-Healing

The success of the 2024 MVPs paves the way for massive industrialization planned for 2025 and 2026. The next step is to extend autonomous automation capabilities to move toward a “Self-healing” infrastructure, capable of repairing minor incidents without human intervention.
