I'm looking for an android app developer who can help us develop a service app that provides the end user the ability to request a certain service from a nearby service provider based on end user location. Basically, the app main function is to connect the end user with a service provider nearby. where, once the end user place the request and select service provider, the service provider should receive the request and then confirms accepting the request. after that, the delivery process starts where end user can see the devilry update on the map. The app is similar to uber concept.
