Summary
👤
SeniorJohn Paraskevopoulos is a Senior Software Engineer based in Athens with 11 years of experience building reliable backend systems, automation tooling, and authentication services across cloud and edge environments. He has shipped core components for the Ubuntu Snap Store and maintained Ubuntu One SSO, leading migrations from Python 2 to 3 and introducing test automation and CI practices. His background spans telecom-grade automation and in-service upgrade tooling at Nokia to identity and federation work for research networks, demonstrating a strong focus on distributed systems, security, and deployment automation. A pragmatic advocate of clean code and design patterns, he pairs deep Python expertise and Unix-centered tooling with hands-on testing (pytest, Jenkins) and orchestration experience around Temporal. Not obviously, he has also played roles in hiring and process improvement—running retrospectives and conducting technical interviews—so he contributes both code and culture. Currently at Corsmed, he continues to apply that blend of craftsmanship and operational rigor to production-grade services.
