Summary
👤
Senior🎓
Top SchoolMichał Janaszek is a Frontend Tech Lead based in Warsaw with 11 years in software and over 4 years focusing on modern JavaScript and React ecosystems. At Inter Cars he leads frontend quality efforts, builds shared component libraries (Lerna, Storybook) used across teams, and drives SSR projects with Next.js while maintaining legacy codebases. He blends pragmatic engineering—migrating jQuery to ES2015+ and collaborating closely with PHP backends and UX designers—with hiring and technical interviewing responsibilities. Comfortable supporting older platforms for wide audiences, he pairs deep hands-on implementation skills with a systems view of frontend architecture. Unusually for a frontend lead, he also has an engineering background in chemistry, reflecting a methodical, analytical approach to problem solving.
