Cross Platform E-commerce App

I want an end-to-end e-commerce mobile application that runs smoothly on both iOS and Android. The core objective is to give shoppers a fast, intuitive way to browse products, add items to their cart, and complete secure in-app purchases. I already have product data and basic brand guidelines; what I need now is the full design-to-code pipeline.

You will handle UI/UX, front-end and back-end development, payment gateway integration, and deployment to the App Store and Google Play. You’re free to choose the tech stack—whether native (Swift + Kotlin) or a cross-platform framework such as Flutter or React Native—as long as the final apps match in look, feel, and performance.

Key deliverables
• Interactive high-fidelity prototypes for sign-off
• Production-ready iOS and Android codebases
• Integrated admin panel for catalog, orders, and user management
• Thorough QA with device testing and bug fixes
• Store-ready builds, screenshots, and release notes

A successful hand-off means I can log in to the admin panel, publish products, and see orders flowing through both stores without crashes or payment issues. If this aligns with your expertise, tell me which stack you’d prefer and a rough timeline so we can get started.
