Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was a config flag. The classics never miss.
Rewrote the hot path in Elixir. Allocations way down. Read the flamegraph before touching anything.
Spent half the day chasing a bug. Root cause: a missing await. Fix was a single index. The classics never miss.
GraphQL + C++ is an underrated combo. Fast to build, easy to reason about. #databases
Boring migrations are safe migrations. Relearned this the hard way again today. #typescript
Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything.
Rewrote the hot path in Zig. CI runtime dropped noticeably. Read the flamegraph before touching anything. #opensource
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Wrote docs for the diff viewer that I'd actually want to read. If the README lies, the code isn't done.
Migrated streaming responses from React to Express. Boring, reversible, no downtime. Exactly how I like it. #typescript
