Android app. Parsing and Graphical Inference of Information from XML

The application must be implemented from Xamarin in C#
As such, the application is already available, but there was no experience in developing C#, so everything is “curved” enough, but it works.
Everything needs to be cleaned up, the graphical interface needs to be improved.
The essence of the application: there is an incoming stream of information in xml format (WebServices). Based on this flow, a certain set of information must be drawn.
Long-term cooperation is possible
The app is tablet-oriented
