Senior🎓
Top SchoolJunhyuk Lee is a Frontend Engineer with 11 years of experience, specializing in React.js and a strong foundation in Ruby on Rails and Node.js. He pairs pixel-perfect front-end craft—typography, color, spacing, lightweight web fonts and micro-animations with Lottie—with data visualization using D3.js to deliver delightful, readable interfaces. Comfortable collaborating directly with designers and distributed teams, he has led frontend efforts at startups and product companies, including a lead role at Presto Labs and current work at flex in Seoul. He writes concise, highly readable code (aiming for <150 lines per module), enforces linting and CodeClimate quality, and adopts cutting-edge React hooks and RC releases. His background includes real-time trading UIs and admin tooling for crypto exchanges, deployment automation with shell/CircleCI, and hands-on product work that drove meaningful user growth. Pragmatic and detail-obsessed, he bridges design sensibility with engineering rigor to ship polished, maintainable front-ends.
