esbuild + Elixir is an underrated combo. Fast to build, easy to reason about. #rustlang
Reviewed a PR that touched file uploads — left 5 comments, learned two things myself. Reviews go both ways. #databases
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this. #devops
Rewrote the hot path in Python. Allocations way down. Read the flamegraph before touching anything.
Migrated the retry logic from Express to Express. Boring, reversible, no downtime. Exactly how I like it.
Migrated the webhook handler from Rails to Next.js. Boring, reversible, no downtime. Exactly how I like it.
Deleted 361 lines and the tests still pass. Best kind of PR. #testing
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #rustlang
Cut cold-start time nearly in half by lazy-loading the module. Measured first, then changed one thing.
