Timothée Jezek, product designer.

I'm a designer with a developer background. I design interfaces with technical constraints in mind, and I collaborate with dev teams as naturally as with design teams.

From the start, I've worked on projects for major accounts (L'Oréal, Renault, French ministries and state agencies) with a lot of autonomy: design systems from scratch, end-to-end interface design, accessibility (Opquast-certified, RGAA-trained), production integration.

AI is part of my daily work. It's an accelerator at every step: tokens, mockups, code, audits, documentation. A multi-agent approach, and a permanent curiosity about new tools.

On the side, I'm building Gatto, a place-discovery app for Paris and Lille. Designed, built and shipped solo: my proof that I can carry a product end to end.
