I am new to Xamarin and i need to create mobile app for iOS ,Android, Windows to expose selected functionality to client top executives.
The functionality needed is
1)Displaying interactive dashboards in the application for top management
2)Ability to download reports based on filters to select a client
3)Authentication to only allow autherised users to access the application using credentials
4)Disabling multiple logins using same user simulataneously
This is new project that i plan to outsource but i need a high level effort estimate of resources/timelines to create the mobile app
