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, from coaching logic and prompt behaviour to edge cases and the screens around them. The medium changed; the rigour didn’t.
Based in Berlin. Open to remote AI product design roles across Europe.

I use AI two ways: as everyday tooling, and as a design material in its own right, from coaching logic and prompt behaviour to the edge cases where models fail people. The tools change every few months; the judgement about which one fits the problem doesn’t.
