Migrated the diff viewer from Express to Next.js. Boring, reversible, no downtime. Exactly how I like it.
Rewrote the hot path in Elixir. p99 latency dropped noticeably. Read the flamegraph before touching anything. #opensource
Reviewed a PR that touched the search index — left 3 comments, learned two things myself. Reviews go both ways. #rustlang
Docker + C++ is an underrated combo. Fast to build, easy to reason about.
Wrote docs for the job queue that I'd actually want to read. If the README lies, the code isn't done. #perf
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.
gRPC + Zig is an underrated combo. Fast to build, easy to reason about.
Cut p99 latency nearly in half by adding one index. Measured first, then changed one thing.
Prod incident: queue depth on the checkout flow blew past every alert threshold at the exact moment of the deploy. Root cause: a silent JSON.parse throw. Fix was a single index. Postmortem: add the metric BEFORE the incident. #buildinpublic
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
