Staff Engineer · Team Lead · Kyiv, Ukraine

Summary

Staff Engineer with ten years in mobile: Android from 2016 (apps used by millions at Trinetix), Flutter from 2019, and team lead since 2020, first on a freelance banking app with a team of four, then at Newfire for healthcare and robotics clients. I set technical direction, design architecture, review code and mentor engineers. My MSc in Software Engineering added backend and frontend, which I use on my own products: the StringLane desktop app and CLI, Supabase and Node.js backends, and web, plus five open-source Flutter packages.
