Mobile Development -- 2

My project is in need of an experienced mobile developer to create an app for both iOS and Android devices. The primary focus of the app is to be an e-commerce platform, although I am open to design and UX/UI suggestions.
I'm looking for a developer with experience in developing apps for both Android and iOS that has a creative eye for design and UX to create a functional and effective e-commerce platform. My goal is to have an app that will be popular among the users, with positive reception stemming from its smooth operation and user friendly features.
This project requires the developer to be detail-oriented and pay attention to all aspects of the app development, from design and functionality to the way users interact and navigate the app. The developer should also be able to provide regular feedback and updates on the progress of the project.
I'm open to suggestions and ideas from the developer as to how best to create an engaging and successful e-commerce app. If you're confident in your ability to deliver a well thought out and top-notch mobile application, please get in touch!
