I’m Thanos Polychronakis, a Senior Backend Engineer based in Thessaloniki, Greece.

I’ve spent 20+ years building and stabilizing backend systems across startups and scale-ups. My focus is system reliability, execution models, and making broken platforms predictable and production-ready.

Most recently I stabilized a non-deterministic Temporal-based workflow platform, driving an architecture reboot focused on determinism, explicit contracts, and testability.

I’ve led engineering teams, delivered full-stack platforms, and taken ambiguous systems and made them shippable. I work best in environments with real technical problems to solve.

Currently open to Senior Backend / Platform Engineer roles. Get in touch: thanpolas@gmail.com
