Migrated the caching layer from Express to Rails. Boring, reversible, no downtime. Exactly how I like it.
Deleted 380 lines and the tests still pass. Best kind of PR. #webdev
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
Delete code before you add code. Relearned this the hard way again today.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #devops
Deleted 334 lines and the tests still pass. Best kind of PR.
Wrote docs for rate limiting that I'd actually want to read. If the README lies, the code isn't done.
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.
Shipped streaming responses today — 2 small commits, all green. Sleep well, future me.
