Back to original languageAbout Baptiste
I am Baptiste, a **Senior Product Designer specializing in Design Systems**, based in Lyon. I lead the structuring of UI practices in organizations where multiple product teams need to speak the same design language — from token creation to daily system governance.
Latest missions:
AtMatrix Requirements(medical sector), I single-handedly led the complete visual redesign of the product, built a UI kit based on Shadcn (v3.1), and oversaw its deployment to development, in tandem with a UX designer, a dev team, and a Product Owner.
AtMichelin(4 years), I first served as Lead Designer for the group's B2B sites (Michelin Pro), then I designed themulti-brand Design Systemfrom scratch, deployed to all internal design teams — including workshops, governance, and executive presentations.
Before that: Lead UI atKardinalon a logistics SaaS solution, and 2 years atAccor'sinternal digital studio.

Thank you for this high-quality work! With Baptiste, we can discuss tastes and colors :). He doesn't hesitate to suggest design ideas different from those requested, and his proposals are often relevant. So far, I am very satisfied and plan to use his services again for new missions!
