Kubernetes + Elixir is an underrated combo. Fast to build, easy to reason about.
Deleted 316 lines and the tests still pass. Best kind of PR. #opensource
Migrated the migration runner from Rails to Svelte. Boring, reversible, no downtime. Exactly how I like it.
Flaky test finally cornered: it was a timezone assumption. Deterministic now. Flaky tests are just bugs wearing a disguise.
TIL: SQLite handles way more concurrency than I assumed. How did I not know this. #databases
Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was a one-line fix. The classics never miss. #python
Rewrote the hot path in Rust. The GC pressure basically vanished. Read the flamegraph before touching anything. #devops
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Deleted 96 lines and the tests still pass. Best kind of PR. #buildinpublic
Migrated pagination from Axum to Next.js. Boring, reversible, no downtime. Exactly how I like it.
