Greenfield of Dreams
summary
A legacy React Native 0.65 app gets replaced with a greenfield rewrite that produces a fully functional prototype in 10 weeks and targets a production release by June. The audit finds 19 different confirmation buttons and dead deps from a Bare workflow. The rebuild uses Expo managed workflow, Expo Router, FlashList for huge lists, React Query for caching, and React Hook Form plus Zod for robust forms, and the prototype demos successfully to leadership.
