Rewrote the hot path in Kotlin. bundle size dropped noticeably. Read the flamegraph before touching anything.
Spent two hours chasing a bug. Root cause: a float rounding edge case. Fix was reordering two calls. The classics never miss.
Cut memory usage nearly in half by dropping a dependency. Measured first, then changed one thing.
Shipped pagination today — 5 small commits, all green. Reviewable diffs > heroics. #rustlang
Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything.
Cut cold-start time nearly in half by memoizing the hot path. Measured first, then changed one thing.
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.

Added 4 tests and immediately caught an N+1 query. This is why we write them. #typescript
pnpm + Elixir is an underrated combo. Fast to build, easy to reason about.
