I design the interfaces of products that control physical things.

I started as a mechanical engineer. For three years at Faurecia I assessed vehicle interiors — CAD models, assembly constraints, perceived quality — before moving to the other side of the same problem: designing the screens those vehicles would carry. That crossing has shaped everything since.

Ten years later, the thread holds. Digital cockpits at Faurecia. Charging stations and intercoms at Hager. A connected security ecosystem at Euro Protection Surveillance. In each case the same question: how do you make
a physical system legible on a screen, when the constraints are real, the stakes are safety-critical, and the engineering team has already made half the decisions?

What I bring is less about interfaces than about alignment. I read technical constraints without needing them translated. I sit in the room with Product and Engineering and I understand both. Most of the design work that actually matters happens before anyone opens Figma — in the arguments about what the product is for, and who decides.

That part has become more valuable, not less, as AI absorbed the production of screens. They have not touched the harder half of the job.

I work in French, English and German, from Strasbourg 🥨, on both sides of the Rhine.
