I need a complete mobile application that lets customers browse and buy products directly from their phones on both iOS and Android. The finished build should feel fast, modern, and secure, with a clean UI that makes checkout effortless. What I expect: • A native or high-quality cross-platform codebase that compiles cleanly for both operating systems. • Core e-commerce flow—product browsing, cart management, and a reliable checkout process. • Secure user authentication and a lightweight admin interface so I can add or update products without touching the code. • Documentation covering how to set up the development environment, link any third-party services you choose, and publish the app to the App Store and Google Play. • Source code handed over in a well-organized repository. I’m open to your recommendations on tech stack and third-party services as long as the result is stable and easy to maintain. If you have live examples of past e-commerce work, please mention them so I can get a feel for your style.
