Konrad Roj

Over a decade of shipping mobile products. The last few years pushing into applied AI — on-device ML, LLM workflows, and the kind of polish that makes software feel inevitable.

Previously Lead iOS at Dispo and Mila, and Senior iOS / Tech Lead at Skyrise.tech. I care about craft, performance, and the last 10% that separates good from great.
