Hello!
I'm a software developer from Serbia, with excellent English skills (C1 certificate) and multiple years of experience in several fields, including Android development, Web / AngularJS development (mainly frontend) and UI design. I feel that my skill set fits your project requirements perfectly.
I've worked with AngularJS in the past, as well as the underlying platform (Android). I think I could complete your project in a matter of days, provided a good description of how you want the app to function.
Looking forward to hearing from you!
