Leonid Fenko is a frontend developer with over 7 years of commercial React and TypeScript experience and a decade in software engineering, specializing in both client- and server-rendered applications and custom build tooling. He has shipped products ranging from high-traffic consumer apps to internal CMS and subscription services, and recently implemented real-time chat and canvas UIs using websockets and Server Components at exactly.ai. An open-source author—creator of react-router-typesafe-routes with 16k weekly downloads—he brings a strong emphasis on type safety, Zod validation, and performant rendering. Comfortable leading small distributed teams, he pairs practical engineering (Webpack/Vite, Tailwind, MJML) with hands-on system design, and outside work he tinkers with Arduino and 3D printing, reflecting a maker’s approach to problem solving.
