I’m ready to bring my physical-goods store to mobile and need a complete ecommerce application that runs smoothly on both iOS and Android. Core flows such as browsing, adding items to a shopping cart, checking out, and tracking orders must feel native on each platform. Account creation, secure sign-in, and profile management are mandatory so customers can save their details and view past purchases. A reliable payment gateway integration—something on the level of Stripe, PayPal, or a comparable SDK—is critical; I want transactions to be seamless and fully encrypted. Beyond the essentials, I’m open to your suggestions on UI frameworks (Flutter, React Native, Swift UI + Kotlin, etc.) as long as the stack you propose guarantees fast load times and straightforward maintenance. Deliverables • Universal iOS & Android app package, ready for App Store and Google Play submission • Intuitive product catalogue, dynamic shopping cart, and checkout flow connected to the chosen gateway • User registration, login, password reset, and basic profile screens with real-time validation • Clean, well-commented source code stored in my Git repository, plus a short hand-off guide If you’ve launched similar cross-platform storefronts before and can meet these points, let’s talk timing and milestones.
