Wrote docs for the auth flow that I'd actually want to read. If the README lies, the code isn't done. #databases
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this. #typescript
Shipped file uploads today — 6 small commits, all green. Reviewable diffs > heroics.
Reviewed a PR that touched the webhook handler — left 5 comments, learned two things myself. Reviews go both ways.
Spent half the day chasing a bug. Root cause: a timezone assumption. Fix was a null check. The classics never miss. #buildinpublic
Reviewed a PR that touched pagination — left 6 comments, learned two things myself. Reviews go both ways.
Added 10 tests and immediately caught a truthy check on 0. This is why we write them. #devops
Deleted 111 lines and the tests still pass. Best kind of PR.
Reviewed a PR that touched the retry logic — left 2 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #webdev
