01The context
Does this sound familiar?
Evolve without ever stopping.
Open your systems to partners.
APIs to expose, interface contracts to structure, key-account partners to onboard. You need someone who speaks both tech and business, and makes the flows reliable end to end.
Decide what to build, and why.
A full backlog, but what's actually worth building? You need someone who starts from the problem and real usage, makes the call by value, and owns what you don't build. Not a PM who works a backlog, but someone who holds the product direction.
02Value proposition
What you can count on
Structure, align and deliver in demanding technical and business contexts.
1
Scope before building
Get the scope right from day one: functional definition, value versus complexity trade-offs, stakeholder alignment.
2
Hold a roadmap on a critical product
Prioritise what matters, make the call between business and tech, and set milestones that hold.
3
Orchestrate systems & API integrations
Coordinate multi-system interfaces and partners: scoping, contracts, testing, delivery.
4
Modernise without disruption
Rebuild journeys and back-office without stopping operations. Security, IAM, cloud migration.
5
Operate in international contexts
Workshops in English, offshore coordination, agile practices adapted to context (Scrum, Kanban, SAFe).
6
IABridge business and tech
Facilitate cross-functional workshops, manage dependencies across systems, communicate clearly at every level.
Put AI in the right place
Where AI creates value in a product, where it doesn't, and how to move from an opportunity to a feature that holds up.
How I integrate AI →03Flagship project
Autossimo, Autodistribution's B2B e-commerce platform.
Client: Autodistribution · Product: Autossimo · Senior Product Owner · since January 2021
Autossimo is Autodistribution's B2B e-commerce platform, at the core of the group's information system: a national platform, 20,000+ automotive professionals, 2 million SKUs, several interconnected ERPs (including SAP) and an API ecosystem open to European partners. English-speaking context, run and build in parallel.
Lead the product end to end: discovery with business teams and the field, vision and roadmap, scoping, value-based prioritisation - including what we decide not to build - then agile delivery and coordination across business, IT, engineering and partners. Four workstreams run in parallel, on a single overall roadmap.
IAI automated product processes and internal flows (monitoring, reporting, alerting) with AI.

Recommendations
In their words.
Recommendations originally written in French on LinkedIn, translated here.
I had the pleasure of working with Nassim on several strategic projects in the B2B automotive sector, where he was my main product-side counterpart.
His deep knowledge of the business, his command of market challenges and his ability to quickly grasp complex technical topics make him a genuine partner for engineering teams. He knows how to bridge client needs, technical constraints and product vision, while keeping every exchange constructive, clear and thoughtful.
I also valued his openness to innovation, particularly around AI, as well as his ability to challenge ideas pragmatically.
I recommend Nassim without hesitation to any company looking for a Product Manager who combines domain expertise, product vision and excellent collaboration with engineering teams.
Yoann BeliotKey Account Manager · Autodistribution I worked with Nassim on a large-scale, structuring project for the relationship between Autodistribution and a strategic client with 250 stores across France. A cross-functional project (sales, accounting, finance, IT). Three years of work. Thousands of emails, hundreds of hours of meetings, internally, with the client and a great many between ourselves. How would I define Nassim's work? Commitment, tenacity, rigour. The result? A collaborative and operational success. Thanks again!
Massinissa KacimiIoT Project Manager · Datanumia I had the pleasure of knowing Nassim, and I can attest to his great professionalism. He is a highly capable person, with excellent know-how and a strong ability to adapt. He approaches every assignment with seriousness, rigour and a real sense of responsibility. Beyond his technical skills, he stands out for his human qualities and excellent communication. He listens, explains with clarity and builds a relationship of trust with colleagues and partners. His commitment, team spirit and constant drive to deliver quality work make him a professional you can count on. I recommend him without hesitation to any organisation or team looking for someone capable, reliable and invested.
Lucas Elslander CampionIndependent insurance broker I had the pleasure of supporting Nassim for several months, and what struck me most was his human quality. Always attentive, available and professional, we immediately built a relationship of trust. A profile as pleasant as it is reliable.

05How I work
What changes when you work with me.
I speak both languages, tech and business.
I challenge an architecture with the devs in the morning, decide a roadmap with the business in the afternoon. Nothing gets lost in translation.
I focus effort where it counts.
Not everything is a priority. I protect what creates the most value and own the trade-offs, without turning the team into a feature factory.
I make run and transformation coexist.
On a critical product, you don't shut down the service to modernise. I structure RUN and BUILD in parallel.
I deliver, and it lasts.
The rituals I put in place still run after I leave. Migrating 20,000 users with zero interruption doesn't happen by chance.
AI is part of my toolkit.
I use it to automate workflows, speed up discovery and design features, in my process and in the product.
I hold the relationship as much as the product.
A critical project always goes through tension. My job is to keep business, engineering and leadership talking when things get tight, and moving in the same direction.

08FAQ
Frequently asked questions
What kind of engagements?+
Short scoping, reinforcement, or long-term product leadership. I adapt to the scope, from a few weeks of scoping to engagements spanning several months or years. Open to a permanent role or a contract engagement.
Remote?+
Yes, seasoned in remote (tools, rituals, async), and I come on-site when the context calls for it.
What if scope shifts mid-way?+
That's the norm in complex environments. I structure rituals to absorb scope changes without losing direction: continuous prioritisation, transparent trade-offs, regular alignment.
How do we get started?+
A 30-minute first call to understand your context. If it is a fit, we get started.
