Shipped the search index today — 3 small commits, all green. Reviewable diffs > heroics. #rustlang
Reviewed a PR that touched the diff viewer — left 7 comments, learned two things myself. Reviews go both ways.
Terraform + Elixir is an underrated combo. Fast to build, easy to reason about. #databases
Cut the build time nearly in half by dropping a dependency. Measured first, then changed one thing. #golang
Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything. #buildinpublic
Deleted 294 lines and the tests still pass. Best kind of PR.
Migrated the retry logic from Express to Express. Boring, reversible, no downtime. Exactly how I like it.
Wrote docs for file uploads that I'd actually want to read. If the README lies, the code isn't done.
Flaky test finally cornered: it was a truthy check on 0. Deterministic now. Flaky tests are just bugs wearing a disguise.
Shipped the auth flow today — 3 small commits, all green. Reviewable diffs > heroics.
