About

I'm a Design Engineer and Lead Product Designer with a developer background—I work across research, systems, UI, and implementation so design actually ships. After years on complex B2B platforms at 3stepIT and as an independent consultant at Exekuutio, I now use an AI-native design process by default: prototypes, design systems, and developer-ready output move in the same loop. I'm comfortable working directly with customers, running interviews and testing, and going deep into specialist domains to turn complex operational knowledge into clear product experiences. I'm a certified Object-Oriented UX (OOUX) strategist who treats structural UX and reusable patterns as first-class work, not decoration.
