Jan Šilhan is a Frontend Architect with over 10 years of experience designing scalable web applications and leading high-performing engineering teams from Brno, Czechia. He specializes in React ecosystems, TypeScript, and modern frontend architecture, driving complex migrations and system redesigns—most notably zero-downtime migrations from CRA to Next.js and an Electron app modernization with big bundle and startup-time wins. Jan builds developer-first tooling and monorepo strategies, authors company-wide component libraries and CI/CD pipelines, and enforces strict TypeScript best practices to reduce runtime errors. His stack spans frontend (Next.js, Expo, Effect-ts), backend runtimes (Node.js, Bun, Deno), and databases (Prisma, Drizzle, Supabase), and he brings a pragmatic testing culture with Vitest, Playwright and Jest. An active open-source contributor, he has fixed types and documentation issues in the widely used Material-UI repository, showing attention to both DX and production stability. He pairs hands-on engineering with team building—recruiting, mentoring and running workshops—to scale sustainable frontend orgs.
