쉽진 않겠지만, 모든 포트를 잇는 프론트엔드 개발자가 되려고 해요. 프론트엔드 안에만 머물지 않고, 백엔드와 맞닿는 지점은 어디인지, UI와 UX가 만나는 자리는 어디인지 들여다보는 걸 좋아합니다.

A frontend developer trying to connect every port — looking at where the frontend meets the backend, and where UI meets UX. Day to day, that means build tooling, design systems, and DX.

  • 🔧 Cut CI release builds 160s → 60s and local builds 1min → 4s (custom Vite plugins, CRA → Rsbuild)
  • 🎨 Maintainer of DaleUI — a Panda CSS design system (RSC, React 19)
  • 📰 Curate Ones To Watch — a frontend newsletter that explains mechanisms, not summaries
  • 🗣️ Spoke at .NET Conf 2025 x Seoul — "Blazor and the Frontend Ecosystem"
🎤 Talks
🌱 Past open source
  • PayloadCMS — richtext-lexical fixes, Korean i18n
  • vapor-ui (goorm) — core, DX, and accessibility details
  • stackflow (Danggeun) — bug fix from app work
