👋 Bio
Systems-oriented Product Designer, specializing in complex and growing products.
I step in to bring structure, consistency, and clarity to evolving product environments, aligning design, product, and tech around a common goal: creating truly useful experiences for users.
Accustomed to taking a step back to view a product as a whole, I design sustainable foundations (design systems, patterns, UX rules) while ensuring every decision remains grounded in real-world usage.
I combine a global vision with a pragmatic approach to build coherent, scalable, and user-centered products — without losing sight of business and technical constraints.
✌️ Outside of work
Outside of work, I spend a good amount of time moving — surfing, swimming, hiking — to maintain a good balance.
I travel whenever possible to gain new perspectives. I read regularly, especially when it's raining and cold!
