Salut, I'm François-Xavier,
a senior product designer in
Paris
I combine deep user research , rapid prototyping, and technical collaboration to turn complex ideas into products people love and trust.
I've designed AI chatbots for labs, launched health tracking apps within months, prototyped XR experiences in days, and built business tools used daily by thousands
How I Work
I design new possibilities, not just fix what's broken.
I quickly immerse in complex domains
Whether it's lab chemistry, autonomous vehicles, or hospitality, you don't need to spend months onboarding me. I ask the right questions and get the real constraints.
I do research that leads to action
I don't guess what users need, I go find out: interviews, field studies, observations in real contexts. I turn insights into concrete design decisions that move your product forward.
I facilitate and align teams
I run design sprints and workshops that get everyone on the same page. Clear communication and structured collaboration mean faster decisions and less wasted time.
I prototype and test rapidly
I create functional prototypes fast. This lets you validate ideas early, avoid costly mistakes, and iterate based on real user feedback before committing development resources.
I collaborate closely with tech
I code a little and understand technical constraints. I propose solutions that actually work in production and save time and reduce friction with your engineering team.
Experience
Senior product designer with 10+ years across France, China, Australia, and Japan. I've designed for lab chemists at L'Oréal, patients with SMA at Biogen, autonomous vehicles at Valeo, and hoteliers at Accor.
My strength is moving into unfamiliar domains quickly. I spend time with users in their actual contexts, understand their real constraints, and design tools that work in the messy reality of day-to-day use.
-
Facilitated and lead 5-day design sprint @Valeo CarLab that quickly lead to Valeo Racer, a new extended reality in-car gaming experience.
-
Successfully conducted field user research and testing in Africa that drastically reduced the time to market for the My Baobab banking app.
-
Designed and conceived MySMA Checker, a mobile app to track symptoms that was built and shipped in less than 3 months.
-
Lead a team of 5 UX/UI Designers @Isobar Melbourne. Set the team's culture, ways of working and best practices that improved collaboration with dev team.
-
I introduced design practices @EPIC - the belgian multi-award-winning agency - that helped delivering work tailored to client needs and reach new markets.
About
Design is about imagining new possibilities. Users don't always need solutions to problems, sometimes they need better ways to work, create, or connect. That's what drives me: exploring what could exist rather than just optimizing what already does.
I've been learning frontend development for over a year to bridge the gap between design and engineering. It's made me a better collaborator and lets me validate ideas through working prototypes instead of static mockups.
I'm also committed to sustainable design practices and believe we need to consider environmental impact in everything we build.
Based in Paris. Available for freelance missions where I can help you validate ideas fast, ship with confidence, and build products users love.

Wait, there's more!
I also enjoy making electronic music, photography and spending time with my 2 daughters. I'm currently learning 3D and animation with Blender.
So far, I have lived and worked in France, Japan, China, South Korea and Australia. I speak English, French, Japanese and conversational Chinese.
