Rockstar🎓
Top SchoolJeroen Reumkens is a frontend engineer and educator with nearly 15 years of professional experience who now runs Frontend.fyi to teach production-ready frontend craft to a global audience. He blends hands-on delivery—working as a freelance frontend engineer on projects like Cal.com and large enterprise clients—with a passion for mentorship and building reusable foundations that empower less experienced engineers. His technical toolkit centers on React, TypeScript, Next.js and modern UI libraries (Tailwind, Chakra, Framer Motion), and he has shipped critical public-facing systems for government, telecom and marketplace platforms. Known for preferring one-time, lifetime course purchases over subscriptions, he creates pragmatic, real-world content that reflects how he actually builds in production. Colleagues describe him as a practical architect who balances quality with delivery speed while keeping team morale high. Based in Amsterdam, he continues to iterate on new teaching formats and tools to broaden his impact beyond individual teams.
