I need them to create a delivery system via application and everything necessary for it to be functional.
The application must receive orders from a customer (order is made through an in-app purchase), send it to the server in the cloud, and the cloud notify my delivery personnel. So there are two applications,
one for customers and one for delivery people.
You must develop the Front-end and back-end of the applications, a database to be hosted in the cloud and a software or page so that I can monitor the entire system.
