Summary
👤
Senior🎓
Top SchoolPiotr Miazga is a Staff Systems Architect based in Warsaw with 12 years of experience designing and delivering backend, full-stack, and high-availability systems. He specializes in architecture, PHP and TypeScript/Node.js, TDD, CI/CD and clean design patterns, and prefers roles focused on backend, full-stack or architectural leadership rather than frontend. A power Linux user and frequent conference/meetup speaker, Piotr combines hands-on coding with systems thinking—recently contributing backend refactors to the core MediaWiki project that powers Wikipedia. He has led engineering teams and consulted across startups and large organizations, driving maintainability, telemetry improvements and deprecation cleanups at scale. Outside of tech he channels precision and risk management as a rally driver, an unexpected discipline that informs his pragmatic approach to reliability and incident response.
