About
14 years designing products that ship — from ecommerce to AI-powered platforms to B2B enterprise systems used by global brands.
I work at the intersection of strategy and execution.
I've turned skeptical enterprise clients into co-development partners, scaled design systems across 7 teams, and used AI-assisted prototyping to validate product bets before committing engineering resources.
Based in Berlin. Currently deep in generative AI — not as a trend to follow, but as a lever for changing how product teams work. I use AI across the full design pipeline — from research synthesis to live prototypes shipped before a single engineer is involved.
Looking for a Staff Product Designer role where design shapes direction, not just screens.
