Who I am

Tallinn-based engineer with a thing for elegant systems

Writing production code since 2016 — started with automation scripts, grew into full-stack products and distributed infrastructure. Most of my work has been for clients across Finland, Germany and the Netherlands, either solo or leading small remote teams.

I value reliability and simplicity over hype. Boring proven solutions when they fit; custom-built when they don’t. Either way, things should work at 3 AM without my phone ringing.

Outside of code: cycling around Tallinn’s Old Town, electronics tinkering, good espresso.
