I’m ready to launch a full-featured e-commerce mobile application and need an experienced developer who can deliver native builds for both iOS and Android from a single, maintainable codebase. The core scope covers: • A smooth product catalogue with advanced search and filtering • Secure cart, checkout and multiple payment-gateway integration (Stripe, PayPal, plus local options) • Account creation with social sign-on, order history, and push notifications • Basic admin endpoints for inventory, pricing and promotions • Clean, modern UI that follows Apple Human Interface and Material Design guidelines Please attach a detailed project proposal that spells out: architecture or framework preference (e.g. React Native, Flutter, Kotlin/Swift side-by-side, etc.), milestone breakdown, estimated schedule, and any third-party services you plan to use for analytics, crash reporting or CI/CD. Prior examples of live e-commerce apps are a strong bonus, but the proposal is the key decision factor. The first deliverable will be a clickable prototype or low-fidelity build so we can iterate on UX before committing to full development. Production-ready source, tested builds on TestFlight and Google Play’s internal track, and concise documentation will complete the engagement. I’m happy to discuss API availability, hosting and any other technical questions once you’ve reviewed the outline above.
