▮ Hi, I'm @shuaixudev

Systems builder
shipping reliability tools
to small teams.

I build CLI and infra tools that turn 3am incidents into morning standups. Currently obsessing over flaky tests and the cost of context-switching for engineers.

shuai@dev:~$ cat now.md

May 2026:
→ Building FlakeKiller v2 with deterministic replay.
→ Reading "Designing Data-Intensive Applications" (3rd time, still learning).
→ Thinking about: why CI feedback loops are still 8 minutes in 2026.
→ Not doing: Twitter, side projects with no users, AI hype threads.

let's build something

I'm currently open to OSS sponsorships, consulting on developer tooling, and full-time roles at infra-focused companies (≤ 50 people).
