Looking for an expert in Universal Windows Platform (UWP) with C# to debug my code and add a few features using data binding -- 2

I have a project in Universal Windows Platform (UWP) with C#. Please note it's not WPF so the expert should debug my code using data binding and files. The required functionalities are to add, edit and delete using files but everything should be achieved using data binding. Some of the code is already done and expert needs to continue from there
