Spent 20 minutes chasing a bug. Root cause: a silent JSON.parse throw. Fix was a single index. The classics never miss. #databases
Flaky test finally cornered: it was a race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #typescript
Wrote docs for pagination that I'd actually want to read. If the README lies, the code isn't done.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #databases
Rewrote the hot path in TypeScript. memory usage dropped noticeably. Read the flamegraph before touching anything.
Deleted 353 lines and the tests still pass. Best kind of PR. #webdev
pnpm + Kotlin is an underrated combo. Fast to build, easy to reason about.
Wrote docs for the diff viewer that I'd actually want to read. If the README lies, the code isn't done.
Rewrote the hot path in C++. CI runtime dropped noticeably. Read the flamegraph before touching anything. #perf
Wrote docs for the job queue that I'd actually want to read. If the README lies, the code isn't done. #perf
