Migrated rate limiting from FastAPI to Express. Boring, reversible, no downtime. Exactly how I like it.
Added 5 tests and immediately caught a timezone assumption. This is why we write them. #python
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Prod incident: error rate on the notification worker went vertical at 03:00. Root cause: an off-by-one in the cursor. Fix was three lines. Postmortem: idempotency is not optional.
Spent 20 minutes chasing a bug. Root cause: a dangling event listener. Fix was a single index. The classics never miss.
Cut bundle size nearly in half by memoizing the hot path. Measured first, then changed one thing. #webdev
Rewrote the hot path in Python. cold-start time dropped noticeably. Read the flamegraph before touching anything. #databases
Added 21 tests and immediately caught a case-sensitive path on Linux. This is why we write them. #python
Deleted 230 lines and the tests still pass. Best kind of PR. #golang
GraphQL + Elixir is an underrated combo. Fast to build, easy to reason about.
