I have taken requirement from the client and then decided the technology we can use for each and every task.and the implemented application

This is on demand doctor application.User can see the doctor near then they can filter the doctor using speciallization.

Then can select and check the qualification experience and cost and can book or can go back.

User can book and see doc to specific position by moving the map to that location.

This application is clone of whatapp all the feature what we have on whatapp has been added and apart from that user have option to send on message to deriver at specific time.
