Migrated the webhook handler from Svelte to Fiber. Boring, reversible, no downtime. Exactly how I like it.
Spent half the day chasing a bug. Root cause: a dangling event listener. Fix was a one-line fix. The classics never miss. #python
The bug is almost always in the last place you changed. Relearned this the hard way again today.
Shipped pagination today — 5 small commits, all green. Reviewable diffs > heroics. #testing
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Profile before you optimize — every time. Relearned this the hard way again today.
Added 21 tests and immediately caught an unindexed query. This is why we write them.
Cut cold-start time nearly in half by precomputing at build time. Measured first, then changed one thing.
Flaky test finally cornered: it was a case-sensitive path on Linux. Deterministic now. Flaky tests are just bugs wearing a disguise.
Wrote docs for the auth flow that I'd actually want to read. If the README lies, the code isn't done. #rustlang
