Deleted 127 lines and the tests still pass. Best kind of PR.
Spent two hours chasing a bug. Root cause: an unindexed query. Fix was reordering two calls. The classics never miss. #buildinpublic
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Cut bundle size nearly in half by dropping a dependency. Measured first, then changed one thing. #python
Rewrote the hot path in C++. query time dropped noticeably. Read the flamegraph before touching anything. #databases
Added 17 tests and immediately caught an unindexed query. This is why we write them.
Cut query time nearly in half by lazy-loading the module. Measured first, then changed one thing.
Docker + Go is an underrated combo. Fast to build, easy to reason about. #webdev
Delete code before you add code. Relearned this the hard way again today.
Flaky test finally cornered: it was an N+1 query. Deterministic now. Flaky tests are just bugs wearing a disguise.
