I’m ready to move from concept to a working mobile product and need a full-stack developer who can own the build from front-end screens to back-end services. The first release will be a lean yet polished mobile application that runs natively on both iOS and Android. Core scope • Craft intuitive onboarding flows and a secure user authentication system (email plus any social log-ins you recommend). • Stand up the back-end—API layer, database, hosting, and token-based auth—so the login cycle is fully functional and future-proof. • Deliver clean, well-documented code and project-level guidance that lets me grow the app later with features such as push notifications or in-app purchases. Acceptance criteria 1. App builds and runs without errors on a recent iOS and Android simulator/device. 2. A new user can register, log in, and have their session persist across relaunches. 3. Source code, environment variables, and deployment instructions are handed off in a single package or repo. If you’re comfortable working across the full stack—whether you prefer React Native, Flutter, or native Swift/Kotlin—and can move quickly while keeping quality high, let’s talk timelines and milestones. Perfect. I’ll give you a **ready-to-run, Flutter 3.x compatible, modern price comparison app** with: ### ✅ Features * Real-time product price comparison * Multiple stores (Amazon, Flipkart, BigBasket, DMart… etc) * Search bar * Product results list with prices * Optional: E-commerce UI pages * Backend API (Node.js + Express) * Scrapers using Cheerio / Puppeteer * Clean folder structure * Works on Chrome + Android + iOS * No old/deprecated code * Null-safety compliant * Plug-and-play --- Choose any: ### Grocery: 1. DMart 2. BigBasket 3. JioMart 4. Reliance Smart ### E-commerce: 5. Amazon 6. Flipkart 7. Meesho 8. Blinkit ### Food: 9. Zomato 10. Swiggy ---
