I’m ready to launch a fully-featured e-commerce application that runs smoothly on both iOS and Android from a single codebase. The core build must include: individual user accounts with profile management, a browsable and searchable product catalog, and a secure, production-ready payment gateway. Here’s what I need from you: — A cross-platform framework implementation (Flutter, React Native or similar) that compiles cleanly for the App Store and Google Play. — Clean, well-documented code tied to a simple admin back-end or easily pluggable API so I can manage products and orders without touching the codebase. — Intuitive UI/UX that follows each platform’s design conventions while keeping brand consistency. — End-to-end testing of log-in/registration, catalog search, cart, checkout and payment flows on physical devices for both operating systems. Hand-off deliverables: 1. Source code with README covering environment setup and build steps. 2. Release-ready binaries (IPA & APK) plus store-listing assets. 3. Brief video or live walkthrough confirming all core flows work. If this scope lines up with your expertise, tell me which framework you prefer and how you’ll tackle user authentication and payment processing.
