About me

Finding the pattern
within the chaos.

I'm a product designer who builds. My edge is seeing the full picture, from micro to macro, reading how systems connect, where they break, and what it takes to fix them.

My background is unconventional. Michelin-starred kitchens, brand systems, and now digital products. Each discipline gave me a different lens. Together they gave me pattern recognition most designers don't have.

Today my workflow is AI-augmented by design, not by accident. I build real products. Klaro, a tax declaration platform, is one I shipped from scratch. I adapt fast, move with the industry, and treat AI as infrastructure. Not a shortcut. A foundation.
