Need an Expert Xamarin Developer (Windows App)

We have an App which is built on Xamarin iOS and we need to build it for the Windows Platform. This will be a long-term project and to start off with, we will do a small paid project of 10-20 hours before the full project is awarded. You must know Xamarin forms and be good with UI. Important: Please send me your portfolio of Xamarin projects and any references to be considered for this project.
