About Thomas

Digital Product Manager with over 15 years of experience, I support organizations in structuring and securing their product roadmaps, from strategic vision to operational execution.

My approach is pragmatic, value and impact-oriented: clarifying issues, prioritizing what's essential, and building useful, high-performing products aligned with business objectives, in close collaboration with business and technical teams.

Over the years, I have managed numerous projects involving marketing, data, tech, and design teams, in various contexts: redesigns, new product launches, customer journey optimization, or strategic alignment between business and technical departments.
What I enjoy most is making projects concrete: transforming an idea into a simple, useful, and profitable product.

My role is often that of a conductor: setting the direction, coordinating teams, arbitrating priorities, and maintaining the overall coherence of the product.
I bring a transversal vision that connects business needs, technical reality, and company strategy.
I also know how to say no to what doesn't create immediate value; a balance that is often difficult to maintain, but essential for effective delivery.

My strengths:
- Solid experience in agile project management and backlog management,
- A genuine sensitivity to UX/UI and product,
- A good understanding of data and marketing challenges,
- And above all, a constant focus on prioritization and ROI.

I work in contexts of product transition or reorganization as well as in acceleration phases where rapid scoping, structuring, and delivery are required.
My goal: to ensure projects advance with clarity, pace, and impact, without wasting time on the superfluous.
