The engineer who thinks like a strategist.

Most product consultants can write user stories. Very few can trace a business goal back to a database schema, and fewer still know how to bridge that gap in a room where engineers, designers, and C-suite stakeholders rarely speak the same language.

With an MSc in Computer Science from Grenoble INP-ENSIMAG and a decade spanning software engineering, business analysis, and product ownership at global scale at Amadeus, La Poste, and GCB Bank, I bring a precision that generalist PMs simply cannot replicate.

I have built payment platforms from zero, rebuilt delivery processes that were haemorrhaging sprint velocity, and shaped multi-region product roadmaps that had to hold up under GDPR, financial regulation, and international compliance simultaneously. I operate at the intersection of business intent and technical reality, and I stay there until the product ships.

I don't just manage backlogs. I build the structural clarity that lets teams move twice as fast, with half the conflict.

Three ways I accelerate your product.

Whether you need strategic direction, embedded execution, or a complete product overhaul, each engagement is scoped to your context and calibrated for measurable outcomes.

01

Fractional Product Owner

Embedded part-time in your team. I own the backlog, lead sprint ceremonies, align engineering with business goals, and make delivery predictable without adding full-time headcount.

  • Backlog architecture and dependency mapping
  • Developer-ready user stories and acceptance criteria
  • Sprint planning, retrospectives and velocity tracking
  • Stakeholder alignment and roadmap communication
  • UAT protocol design and release coordination
02

Product Strategy & Roadmap

When direction is unclear or the roadmap is a wishlist, I bring rigour. From OKR definition to prioritisation frameworks, I create the strategic scaffolding your team can actually build against.

  • Product vision and positioning workshops
  • OKR definition aligned to business strategy
  • Market and competitive analysis
  • Feature prioritisation using RICE, MoSCoW and impact mapping
  • Go-to-market strategy and launch planning
03

End-to-End Delivery

For teams building something new or rebuilding something broken, I take ownership from discovery through to launch, managing complexity across cross-functional teams and regulated environments.

  • Discovery and user research facilitation
  • Technical requirements and API design
  • Cross-functional team coordination
  • Compliance and regulatory integration including GDPR
  • KPI frameworks and post-launch analytics

Built at global scale.

What working with me feels like.

What made Marck-Edward exceptional was his ability to step into a team where no backlog existed and build it from nothing, with full dependency mapping across four line teams. That level of structural thinking is rare even in senior POs.

LM
Line Manager
Amadeus, Nice

He writes acceptance criteria that engineers actually understand. That sounds basic but it cuts review cycles in half. Our rework dropped noticeably within the first two sprints of him joining.

SE
Lead Software Engineer
Amadeus, Product Platform

Marck-Edward bridged a gap we had struggled with for months. He could discuss technical architecture with the dev team in the morning, then present a clean roadmap to C-level stakeholders in the afternoon. That fluency is invaluable.

PM
Product Manager
La Poste Mobile

He inherited an app with a 3.8 rating and user complaints we had not properly actioned. He systematically mapped the feedback to features, pushed it through the pipeline, and we hit 4.4 within six months. Results-driven is an understatement.

Where I deliver most.

01

Travel Technology

Deep operational experience inside Amadeus, the world's largest travel tech platform. I understand airline, hotel, and agency workflows at API and product depth.

02

Fintech & Banking

From building payment processing infrastructure in Ghana to delivering compliance-critical financial features for La Poste's 3M-user app, I navigate regulated fintech with precision.

03

Scale-ups & Digital

Startups and scale-ups needing senior product leadership without the full-time overhead. I bring enterprise-grade process to fast-moving teams without slowing them down.

04

International Products

Products that must work across multiple regions, languages, and regulatory frameworks. I have shipped in Europe, Africa, and across Asia-Pacific markets simultaneously.

05

Regulated Environments

GDPR, financial services compliance, banking standards, audit readiness. I build compliance into product design from day one, not as a retrofit at launch.

06

AI-Augmented Products

Certified in AI Product Management. I help teams identify where AI creates genuine product value and define the requirements to integrate it responsibly at scale.

How I Work

From first call to shipped product. Here is what to expect.

01 · Discovery

Understand the real problem

I begin every engagement by mapping the gap between your current state and your strategic intent, interviewing stakeholders, auditing existing artefacts, and identifying the blockers most teams don't name out loud.

02 · Structure

Build the foundation

Backlog architecture, dependency mapping, roadmap sequencing. I create the structural clarity your engineers need to move fast and your leadership needs to trust the timeline.

03 · Execute

Drive delivery

Sprint by sprint, I maintain alignment between engineering output and business goals. Clear acceptance criteria, proactive risk flags, and release coordination that doesn't require chasing.

04 · Measure

Prove the value

Every engagement ends with documented outcomes. KPIs moved, velocity changes, delivery improvements. You will always know exactly what the engagement delivered.

Built on rigorous foundations.
