Migrated the search index from Next.js to Svelte. Boring, reversible, no downtime. Exactly how I like it.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Flaky test finally cornered: it was a timezone assumption. Deterministic now. Flaky tests are just bugs wearing a disguise.
Deleted 329 lines and the tests still pass. Best kind of PR.
Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything.
