Summary
👤
Senior🎓
Top SchoolMarcin Pietruszka is a Staff Engineer with nine years focused on modern React and React Native ecosystems and over two decades of hands-on development experience. He has shipped production-grade, Google-standard React code for the popular open-source Web Stories editor and led a universal React+React Native codebase that runs Web, iOS, and Android for the longstanding iOne BlackPlanet social platform. Equally comfortable writing high-quality UI components and designing cross-platform architecture, he also builds developer ergonomics—mentoring teams, improving code review practices, and raising automated testing standards. A pragmatist who bet on React in 2015, Marcin combines deep front-end craft with the ability to learn new technologies quickly and evaluate their real-world value. Based in the Cracow metro area, he’s now seeking an ambitious React/TypeScript or React Native project for 2026 and beyond.
