Backend engineer from Taiwan, mostly living in the Node.js / TypeScript world — NestJS APIs, end-to-end typed contracts, and the plumbing that keeps a product running. Most of my work happens in private repos, so my GitHub is quieter than it looks.

Lately I've been digging into contract-first API design (oRPC + Zod) and ATDD against real databases with Testcontainers — fewer hand-maintained schemas, more tests that actually catch things.
