I’m building a cross-platform e-commerce application for both Android and iOS and need one full-stack engineer to take it from concept to store release. The core of the product is traditional online shopping—catalog, cart, checkout—yet I also want it to feel social. Shoppers will create rich user profiles, exchange direct messages, and see an activity feed that highlights recent purchases, reviews, and follows. In short, they can buy and interact in the same place. I already have basic wireframes and a feature list; what I lack is the technical muscle to transform them into production-ready code plus a rock-solid backend. I’m flexible on the tech stack as long as the end result is performant, secure, and maintainable. If you regularly work with Flutter, React Native, or native Swift/Kotlin and enjoy architecting REST / GraphQL APIs, that’s exactly the background I’m after. Deliverables • Fully tested Android & iOS apps ready for Google Play and the App Store • Scalable backend with user, product, order, and social modules • Simple admin dashboard for catalog and user management • Clear build/run documentation and hand-off support I haven’t settled on a payment gateway yet, so your guidance on the best option—and its integration—will be valued. If this mix of shopping and social sounds like the kind of build you excel at, let’s talk details and timelines.
