Summary
🤩
Rockstar🎓
Top SchoolDaniel Trojanowski is a Software Engineer and Front-end Architect with 13 years of experience building production web applications and developer tooling from Krakow, Poland. He blends deep front-end expertise in TypeScript, React and Apollo/GraphQL with backend work in Python and Node.js, and operational know-how managing Kubernetes clusters. At semadoX he guides front-end architecture while still contributing hands-on code, and at Omni Calculator he helped ship complex interactive tools backed by PostgreSQL and GraphQL. An active open-source contributor, he maintained react-apollo-hooks enhancements—adding TypeScript defs, refactors and new hooks to improve developer ergonomics and cache performance. Comfortable across the full stack, he pairs pragmatic engineering with a product-minded approach informed by an academic background in Computer Science and Econometrics. Colleagues describe him as a detail-oriented architect who prefers solving hard UX-data integration problems rather than just implementing features.
