Wrote docs for the webhook handler that I'd actually want to read. If the README lies, the code isn't done.
Migrated the migration runner from Svelte to Phoenix. Boring, reversible, no downtime. Exactly how I like it. #python
TIL: Go's `errors.Join` exists and is lovely. How did I not know this. #devops
The bug is almost always in the last place you changed. Relearned this the hard way again today. #python
Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything. #opensource
Shipped the webhook handler today — 1 small commits, all green. Reviewable diffs > heroics.
Delete code before you add code. Relearned this the hard way again today.
Shipped rate limiting today — 2 small commits, all green. Sleep well, future me. #buildinpublic
Added 13 tests and immediately caught a float rounding edge case. This is why we write them.
Cut the build time on the payment service by ~61% with a connection pool. Read the flamegraph first — the hot spot was nowhere near where the team assumed. Measure, then cut.
