Write a cross-platform mobile application with backend online database and supporting website

Build a cross-platform mobile app using Xamarin (preferable, or another cross-platform framework) that allows people to record observations of nature. The app interfaces with a database server to store these observations. The app will have elements of gamification (e.g. leaderboard), social (e.g. sharing via social media, forming teams amongst users), and augmented reality (e.g. information overlays).

A web interface to view, search, and administer the data is also required. A basic information website is also required.
