Hi,
I'm Hasnain. I has been working with Xamarin Android for more than a year now and i understand the challenges that come with it. Especially designing the UI , because Xamarin designer is not as good as android Studio designer. I can get this done in 2 days if you award me the project.
I have seen the attached screen shot and it is absolutely not a problem for me to design your pages. Seeing as they will be similarly themed to the sign up screen.
Also you do not have to worry about the UI being compatible with Xamarin as i will make sure the app runs fine before I deliver it to you.
I hope you award me the project.
Thanks.
