Project description:
"I’m ready to move my online store from the browser to customers’ pockets and need a developer who can deliver a polished e-commerce app for both iOS and Android. The core of the project is straightforward: shoppers must be able to browse my existing catalogue and complete purchases through a fully functional, secure payment gateway.

I already have product data, imagery and a web-based checkout flow, so you can either build on my current API or propose an alternative approach that keeps everything in sync. A clean, responsive UI, smooth navigation, and fast load times are non-negotiable; beyond that I’m open to your suggestions on architecture, whether you prefer Swift/Kotlin or a cross-platform framework such as Flutter or React Native.

When you hand the project back to me I expect:
• A production-ready iOS and Android build, published to TestFlight and an equivalent Android testing track.
• Payment gateway integration fully tested in both sandbox and live modes.
• Source code, documentation, and brief hand-off notes so my in-house team can handle routine updates.

If you’ve shipped an e-commerce app before and can point me to live examples, I’d love to see them. Let’s get started." (client-provided description)
