I need a full-featured e-commerce application delivered for both iOS and Android. At its core the app must let shoppers create secure user accounts and rich profiles, browse a well-organised product catalogue, locate items quickly through filtered search, and complete purchases through an integrated payment gateway that handles major cards and digital wallets with PCI compliance. The flow I have in mind starts with a clean onboarding sequence, moves into personalised product discovery, and ends with an effortless checkout. I will supply brand guidelines, product data and API documentation for inventory and order processing; your job is to turn that material into a fast, reliable mobile experience that feels completely native on each platform. Please base the build on a maintainable cross-platform stack—React Native, Flutter or another modern framework that keeps a single codebase yet still respects iOS and Android design conventions. The finished package should include: • Source code with clear, commented structure • Compiled builds ready for TestFlight and Google Play internal testing • Basic analytics hooks so I can track installs, sessions and conversions • A concise hand-off document covering environment setup, build steps and store submission requirements Acceptance criteria will be met when the app passes store review in its first submission round, processes test transactions end-to-end, and demonstrates stable performance across the latest two OS versions on common devices. Let me know your proposed timeline, any relevant live app examples, and preferred tech stack so we can lock in milestones and move straight into development.
