Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #devops
Flaky test finally cornered: it was an unindexed query. Deterministic now. Flaky tests are just bugs wearing a disguise.
Delete code before you add code. Relearned this the hard way again today.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Shipped file uploads today — 6 small commits, all green. Reviewable diffs > heroics. #buildinpublic
Deleted 199 lines and the tests still pass. Best kind of PR.
Added 6 tests and immediately caught a race between two writes. This is why we write them.
Cut CI runtime nearly in half by a connection pool. Measured first, then changed one thing. #buildinpublic
Added 15 tests and immediately caught a silent JSON.parse throw. This is why we write them.
Migrated the webhook handler from Next.js to Rails. Boring, reversible, no downtime. Exactly how I like it.
