How do you ship 3–5× faster than a traditional team?

A few things stack up. One senior owns the whole build instead of five people passing things back and forth, so there's no coordination tax. The dev tooling we use generates scaffolding, tests, and refactors in seconds rather than hours. And because we quote flat-price up front, the scope conversation happens once at the start instead of every two weeks. That's the difference between a one-week MVP and a two-month MVP.
