§ 04  SYSTEMS

Built to be understood and maintained.

Your product needs to stay understandable after launch. I make the important decisions early: where data lives, who can access it, and how the system recovers when a service fails.

You get those decisions in writing, alongside the code, so the next feature or the next engineer has a clear place to start.
