I have a project that needs a Xamarin cross-platform solution. I will build the back-end on my own in PHP, so it's only the app itself. Communication is REST and JSON.
Basically it would require:
Login with Facebook
Login with username/password (no sign up)
My membership cards
TableView with list of memberships perhaps with a picture
View whatever is in your profile
For authentication I am thinking JWT.
Design and ease of use is very important.
The project will need upgrades in the future, so I will need all of the source code for the project when it's done. Perhaps assistance with maintenance until I get the hang of it. I'm an Objective-C developer myself and I only did iOS applications, so C# is new to me.
Does this sound realistic to you?
