Capabilities

能力與證據

每一張卡片代表一項工程能力，下方列出代表性 PR 作為「我做過、且被合併」的證據。

Frontend Engineering & 大規模 Codebase 重構

8 merged · 2 repos

在 Jaeger UI 跑 20 個 PR 的系統性 refactor series：把 React class components 轉成 hooks-based functional components， 跨 plexus graph library 與 trace views。能在大型 codebase 做漸進式 migration 而不破壞既有功能。
