About Thomas

For 16 years, I have been assisting public and private organizations in the design and improvement of digital products and services (strategic workshops, user research, product scoping, prioritization, interface design / prototyping).

I work with major players in the public sector, e-commerce, and financial services (B2C, B2B, B2E markets). This diversity has taught me to quickly identify user issues and transform them into product opportunities.

On a long-term mission, I establish the research strategy with you, conduct exploratory interviews and user testing, lead co-design workshops, and translate field insights into actionable product decisions (perfect for pivoting your product). On a short mission, I audit your product and design key user journeys or screens in your funnel to maximize conversions and retention. I prototype rapidly to unblock stalled projects and build consensus within teams.

I automate your product exploration with AI workflows (Claude Code, MCP, RAG, custom skills) that my experience allows me to frame and manage to rigorously transform your qualitative and quantitative data into strategic decisions (goodbye to hallucinations).

With a master's degree in cognitive psychology (Université Paris Cité) and a master's in digital product and service management (Gobelins), I am also a certified Scrum Master, Product Owner, and Opquast (955/1000). I train tech professionals (PO/PM, designers, developers) in Design Thinking and Design Sprint.

Measurable Results (recently):
+2.3 points in satisfaction on some of the most used administrative procedures in France
+90 user tests
~50 exploratory interviews
+30 strategic workshops

+10 DSI of public services supported, including priority government policies (PPG)
