France-based Product Designer with a San Francisco mindset. Dedicated to minimalist aesthetics and functional clarity.
I specialize in crafting seamless experiences for Mobile, SaaS, and Design Systems, bridging functional clarity with scalable architecture.
I’am currently leading product design at chilli, an app empowering climate action. I also co-founded Frame-ux, a design studio, alongside my brother.
