The notes here are about the judgment calls along the way - written for the people who run companies, not only the people who write code.

Approach
How we work.
Most software problems are scoping problems, so we start by narrowing. Proven services carry the parts that should be boring—authentication, payments, infrastructure—and invention goes where it earns its keep. Everything is built to be maintained by whoever comes next.
Decide what not to build
A smaller product that works beats a larger one that nearly does. Scope is the first design decision.
Standard where it should be
Authentication, payments and infrastructure come from proven services, integrated carefully. Invention is spent where it makes a difference.
Built to be maintained
Clear structure, small commits and honest documentation, so the next person—or the next model—can pick the work up.
