Spent most of the afternoon chasing a bug. Root cause: a silent JSON.parse throw. Fix was a single index. The classics never miss.
Migrated the migration runner from Rails to React. Boring, reversible, no downtime. Exactly how I like it.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #opensource
Shipped file uploads today — 1 small commits, all green. Reviewable diffs > heroics. #opensource
Spent two hours chasing a bug. Root cause: an off-by-one in the cursor. Fix was three lines. The classics never miss. #perf

TIL: SQLite handles way more concurrency than I assumed. How did I not know this. #databases
Shipped pagination today — 4 small commits, all green. Reviewable diffs > heroics.
