About

Brands and interfaces, designed as one. For work that actually matters.

I am Mehdi, a UX/UI designer and art director based in Strasbourg. I shape the brand and the product side by side, so the identity, the type and every screen tell the same story. Fluent in French and English, I'm drawn to ambitious projects with something real at stake.
