Senior

Byungwoo Lee is a seasoned software engineer and long-time open-source committer with 14 years of experience building browser and web-platform features at companies including Samsung, Igalia, and Chromium. He brings deep C/C++ and web platform expertise—HTML/CSS/JavaScript/Java—alongside practical backend and cloud skills (Linux/Android, Spring, MySQL, Redis, AWS, Docker, Jenkins). His recent Chromium and Web Platform Tests contributions show a focus on robust build hygiene and advancing selector semantics (notably :has()) across widely used projects. Comfortable across front-end and systems code, he pairs low-level problem solving with production deployment know-how. Based in South Korea, he blends long-term product engineering at Samsung with active, meticulous open-source work that keeps major browser codepaths healthy.
