Hi there - I'm Aly,
I've seen your post and I'm interested. I've had much experience with XAML either it WPF, UWP, or Xamarin Forms. I've used both XAML 2006 and XAML 2009. I've practiced many XAML aspects including binding, static extension, value converters, custom markup extensions, data templates, control templates, styles, custom controls, user controls, and resource dictionaries. Before being able to estimate a final budget, I need to be fully aware of requirements. I'd like to know more about the app. Don't hesitate to contact me to talk further.
Sincerely,
Aly El-Haddad
