Make an Android App with Parse Server as back-end

I need someone who can create an android 4.1+ app with self-hosted Parse Server as back-end. The app will allow the user (salesclerk) to record sales transaction and manage the inventory (CRUD). There will be a dashboard to let the users to have information of the store real-time. This app require to use passwordless sign in using SMS authentication. It is okay for me if you use open-source lib -- as long as no bug involved. So you don't have to code every single thing by yourself. I prefer to use self-hosted Parse Server as back-end to accelerate back-end development process. But if you have other solution technology to simplify back-end dev then I will consider it.
