Janclab Matija Janc · Platform & AI engineer

I build AI-first systems — and everything on this page is running, not a screenshot.

18 years of building, plus personal projects across AI, games, mobile, IoT and automation. Every panel below is the real thing — a phone that becomes a gun, a car you drive from your pocket, a concierge that answers guests at 2am.
