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