đź‘‹ About me
I'm Kevin, an expert in Design Systems, UI Design & Front-end Development, based in Paris.
My core business: bridging the gap between design and tech teams to build coherent, scalable, and truly adopted interface systems. The goal is not just to deliver a clean component library. It's to build a design system that truly lives within the product, both on the design and code sides, with the documentation and processes that allow teams to adopt it without me.
For 12 years, I've worked as a freelancer for hyper-growth startups, large corporations, and public services. I implemented Yousign's first design system during their complete overhaul, structured Accor's mobile DS (iOS & Android) for about thirty design and tech contributors, and rebuilt Grist's Figma foundations for DINUM. Each context has its complexities, but the approach is the same: audit the existing, structure the foundations, onboard the teams, and leave something that lasts.
What sets me apart: a dual design and front-end perspective that allows me to work as effectively in design tools as in JavaScript, and to speak the same language as developers. This is where I have the most impact, at the intersection of design and code, where the two logics must coexist.
✌️ Outside of work
Sports are central to my daily life: running, weight training, and a particular focus on nutrition and recovery. Hiking too, in forests, mountains, or cycling 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 an avid consumer, always up for a chat over a coffee.
