Summary
🤩
Rockstar🎓
Top SchoolJong Seo is a Tech Lead based in Seoul with six years of front-end engineering experience focused on productivity tooling and developer experience. He advances team velocity by building custom ESLint rules, devtool extensions, and running knowledge-sharing seminars, while also diving into the toughest, "impossible" bugs to learn and improve systems. At Creatrip he progressed from Frontend Engineer to Frontend Lead and now Tech Lead, shaping both code and process for a consumer-facing product. His open-source work includes a React+Vite TypeScript Chrome extension boilerplate where he upgraded React, improved HMR and error handling—demonstrating practical improvements to developer workflows. Jong combines a management-science background with hands-on UI and tooling expertise, preferring to "go right" rather than just go fast. He’s known for making small infrastructure and dev-experience wins that disproportionately speed teams up.
