app buildout

I'm looking to hire a professional freelancer to help build a mobile application for both iOS and Android that supports in-app purchases. This project will include designing and creating an app with a UI that is based on my own ideas. Having experience in coding for both Android and iOS will be helpful. I'm looking for someone who not only can design a great user experience, but also has a good understanding of the application's core functionality and payment services. The successful freelancer should have experience in creating apps that look great and are easy to use, while also able to incorporate the payment gateway, such as in-app purchases, so that users can make secure payments. If you feel you have the skillset necessary to build an application that meets these needs, I'd be happy to discuss further details with you.
