App development

I am looking for a skilled app developer to help bring my project to life. I need the app developed for both iOS and Android, and it should have some pages, and options and radio buttons leading to other pages. It is going to be connected online to a server so I need you to leave space for that. As far as design preferences go, I am aiming for a minimalistic feel for the app. The developer should be able to create a reliable and attractive app for both platforms that meets my needs.
