Refactoring to understand and "vibe coding"

If you want to onboard someone onto a new codebase, let them rewrite part of it. They’ll learn a lot from the process, but crucially they’ll become an instant subject-matter expert on the part they rewrote. With a few refactors, you can go from a situation where you’re the only go-to engineer to a situation where multiple engineers on the team can take ownership. That’s the only sustainable way to run a large codebase.

This is exactly what I’ve been doing at work for the last six months, and now I’m the subject matter expert on a small number of essential components of the system.

These sneaky buggers… 😂
