Changwon Yoon

Senior Frontend Engineer · 한국어

I turn messy requirements into clear next steps.
I build tools for the repetitive parts, and write about the decisions behind the code.

Selected work

  • react-query-helper · Generate TanStack Query options from TypeScript APIs.
  • next-test-mode · Reproduce API failures and delays without changing production code.
  • virtual-keyboard · A React input component with direct control over Korean text composition.

Away from the backlog

I studied architecture and write essays. Some of those essays became a constellation you can explore.
