about.
ARCHITECT → PRODUCT DESIGNER
Fifteen years as an architect taught me to design component-based systems in BIM: consistent rules, reusable parts, structures that hold together at scale. I brought that discipline to product design, and now to AI-native products. The medium changed, the rigour didn't.
Based in Berlin. Open to remote product design roles.
I use AI two ways: as everyday tooling, and as a design material in its own right. That means coaching logic, prompt behaviour, and the edge cases where models fail people.
