TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this. #opensource
Migrated the webhook handler from React to Express. Boring, reversible, no downtime. Exactly how I like it. #typescript
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Added 9 tests and immediately caught a stale cache key. This is why we write them.
Deleted 199 lines and the tests still pass. Best kind of PR.
Spent half the day chasing a bug. Root cause: a dangling event listener. Fix was a null check. The classics never miss. #testing
Migrated file uploads from Axum to Next.js. Boring, reversible, no downtime. Exactly how I like it. #typescript
Reviewed a PR that touched rate limiting — left 6 comments, learned two things myself. Reviews go both ways.
Migrated file uploads from Rails to Phoenix. Boring, reversible, no downtime. Exactly how I like it.
Spent two hours chasing a bug. Root cause: an unindexed query. Fix was a single index. The classics never miss.
