Reviewed a PR that touched streaming responses — left 6 comments, learned two things myself. Reviews go both ways. #golang
Migrated rate limiting from Phoenix to Axum. Boring, reversible, no downtime. Exactly how I like it. #databases
The bug is almost always in the last place you changed. Relearned this the hard way again today.
Vite + Swift is an underrated combo. Fast to build, easy to reason about. #webdev
Deleted 309 lines and the tests still pass. Best kind of PR.
Spent two hours chasing a bug. Root cause: a race between two writes. Fix was a null check. The classics never miss.
Rewrote the hot path in TypeScript. Allocations way down. Read the flamegraph before touching anything. #devops
