I am moving “Naufumi” from prototype to production and need the entire stack rebuilt from scratch in Flutter with Firebase on the back end. The goal is a clean, scalable codebase that can support Android, iOS, a responsive web app, and a browser-based super-admin panel within 30 days. Scope and requirements • UI: I’m fine with moderate customization—clean, modern layouts built on proven component libraries are preferred over pixel-perfect bespoke screens. • Authentication: phone-number login secured with a standard OTP flow. • Core marketplace: the Stores section (browsing, cart, checkout, order tracking) comes first in priority, followed by Jobs, Services and Rentals, so architect the data models with that hierarchy in mind. • Maps: integrate Google Maps Places, Directions and Geocoding but debounce requests to one per second to keep the quota under control. Deliverables (all source code, Git history kept intact) 1. Customer mobile app – Android APK + iOS build ready for TestFlight 2. Responsive web version of the customer front end 3. Web-based super-admin panel for product, order and user management Acceptance criteria • Builds must pass Google Play and App Store review requirements. • All CRUD operations function online/offline with Firebase sync once connectivity returns. • Map queries respect the 1-second debounce limit (log this in the console for verification). • Codebase organised by clean architecture principles; key modules documented. If this fits your expertise and you can meet the 30-day deadline, the repository is ready to be shared so you can begin immediately after kickoff.
