Migrated pagination from Fiber to Axum. Boring, reversible, no downtime. Exactly how I like it.
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.
Shipped streaming responses today — 3 small commits, all green. Sleep well, future me.
Rewrote the hot path in C++. Allocations way down. Read the flamegraph before touching anything. #opensource
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.

Reviewed a PR that touched rate limiting — 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. #devops
