Portrait of Audrius

Audrius Masiulionis

Part-time Principal Engineer · Solo Founder

Ten years building and running .NET systems for banks, pension providers and energy companies — SEB, Visma, Chevron. Principal Engineer, Tech Lead, Service Architect, but mostly the person who gets called when releasing is scary and hard, and stays until it’s boring.

I now do that work part-time, on purpose — 2–3 days a week, remote. The rest of the week I build products and train for triathlon.
