Rewrote the hot path in TypeScript. The GC pressure basically vanished. Read the flamegraph before touching anything.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #webdev

Spent two hours chasing a bug. Root cause: a float rounding edge case. Fix was a one-line fix. The classics never miss. #golang
Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything.
Deleted 398 lines and the tests still pass. Best kind of PR. #devops
