I’m launching an e-commerce mobile experience and need it released simultaneously on iOS and Android. The core scope covers everything from building the product catalogue and shopping-cart flow to integrating a secure payment gateway, user authentication, order tracking, and basic push notifications. A lightweight admin panel or clear API hooks for product and order management will also be needed so my team can keep stock and listings up to date without developer intervention. Clean, performant code, adherence to each store’s submission guidelines, and a UI that feels truly native on both platforms are non-negotiable. Please highlight your experience shipping comparable multi-platform retail or marketplace apps, noting any frameworks (Swift, Kotlin, Flutter, React Native, etc.) you prefer and why—they’re all on the table as long as the final build is stable, snappy, and easily maintainable. I’ll walk you through the brand assets, wireframes, and endpoint documentation once we agree on timelines. Final deliverables include: • Fully functional iOS and Android builds ready for App Store & Play Store submission • Source code in a private repo with clear README for setup and deployment • Brief hand-off session or video explaining project structure and future update process If your background shows you’ve done this before and can hit deadlines, let’s talk.
