Hi there.

👋 About me

I'm Kevin, expert Design System · UI Design & Front-end Development, based in Paris. My core mission is to bridge design and tech teams to build consistent, scalable systems, for every kind of screen. The goal is not just to deliver a clean component library. It's to build a design system that really lives in the product, both design and code side, with the documentation and processes that allow the teams to take over without me.

For 12 years, I've been working as a freelancer with startups in hypergrowth, large groups and public services. I set up the first design system at Yousign when they completely redesigned their product, structured the mobile design system at Accor (iOS & Android) for a team of thirty design and tech contributors, and rebuilt the Figma foundations for Grist for the DINUM (Bêta.gouv). Each context has its complexity, but the same approach: audit the existing, structure the foundations, embed the teams, and leave something that lasts.

What sets me apart: a double design and front-end reading that allows me to work in both design tools and JavaScript, and speak the same language as developers. That's where I have the most impact, at the intersection of design and code, where the two logics must coexist.

I regularly share my experience through conferences (design system, front-end architecture) and articles on this page.

✌️ Outside of work

Sport takes up a central place in my daily life, running, strength training, and a particular focus on nutrition and recovery. Hiking too, in forests, in the mountains, or by bike on long routes (Vélodyssée and Via Rhôna…).

Music is another constant, digging for sounds, mixing, creating, I always come back to it.

Football is my other great passion, matches, shows, debates, tactical analysis… I'm a dedicated consumer, always up for talking about it over a coffee.
