I’m a Senior Product Designer with over 7 years of experience, designing digital products that are useful, consistent, and scalable.

I started in a web agency and went on to work in industrial environments (Airbus), then in more agile contexts (BeApp, La Capsule), before joining PrestaShop, where I currently hold a strategic role at the intersection of design, product, and user research.

I focus on structuring Design Systems, equipping teams through Design Ops practices, and building a scalable user research system that turns insights into collaborative, actionable processes.

🎯 My goal: to make design a tangible lever for product performance, team alignment, and long-term user value.
