React Native E-Commerce App Developer needed - Long term relationship

I’m kicking off a brand-new e-commerce app and I’d like to partner with someone who can stay involved well beyond the initial launch. The project is starting from scratch, and I want it built in React Native so we can maintain a single code-base for iOS (and later Android)... (Budget: $8 - $15 USD, Jobs: Android, API Integration, iOS, iOS Development, iPhone, Payment Gateway Integration, PhoneGap, React Native)
