about
Most of my work lives at the intersection of mobile products, developer tooling, and AI.
I care about the parts that make software last: clear architecture, fast feedback loops, and systems that are easy to evolve.
Based in Białystok, Poland.

Mobile Apps
Cross-platform apps — from first commit to store release.
