Build me an App

I am looking for an experienced app developer to build me an app that is compatible with both iOS and Android platforms. I also require a back-end component to be included. I do not have a pre-existing design or style guide. The app should be developed with intuitive navigation, attractive design, and the latest technology for a great user experience. It should also be optimized for search engines and have cross-platform compatibility for maximum reach. The developer should have a good understanding of app development, API integration, and mobile OS platforms. The quality of the app should exceed industry standards and meet my exact requirements. I am looking forward to seeing what amazing apps the right candidate can build!
