Leaderboards webpage build

We need to create a backend and frontend for a leaderboards webpage. The backend will expose a simple API over HTTPS. Through the API it will recieve AES encrypted data in form of JSON string and insert it into database. The webpage should have a form of a world map. Based on the data the interface should in real time show which regions of the map are updated - sort of like [login to view URL] There would also be a dedicated place for the top regions.
