Summary
👤
Senior🎓
Top SchoolOskar Barcz is a senior software engineer and engineering leader based in Warsaw with 9 years of experience building scalable architectures and founding maintenance and SSO platforms for SMEs. He has led high-stakes technical integrations and business-facing initiatives—most notably the Piwik PRO/Cookie Information merger, building a Maintenance & Support unit at Boldare, and architecting services for TUI and Saudi Arabia’s MHRSD. Equally committed to tech-for-good, he leads and mentors a 60-person volunteer engineering community, driving product strategy for social platforms like MyPolitics and Działaj.org. Technically fluent across PHP, Go, JS/TS and cloud-native stacks (Kubernetes, Azure), he pairs hands-on refactoring and microservices design with C‑suite collaboration to shorten release cycles and reduce operational risk. He blends product sensibility and process design—often implementing metrics (MTTD/MTTR/SLA) and change-management—to make complex systems auditable and resilient. Outside work he speaks at conferences and pilots aircraft in his spare time, a hint at his appetite for structured risk and continual learning.
