I’m a senior product designer with over 7 years of experience designing digital products that are useful, consistent, and scalable.

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

</aside>

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 boosted with AI.

TLDR: 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.
