Hello Sir/Madam, As per the requirement, I can understand that you need a mobile application that make calls over network securely. However, it is not yet much clear and the secure things needed to be implemented in the application. Regarding my experience in mobile app development, I am into mobile app development since past 4 years concurrently both on android as well as iOS. So I will be able to handle both things at a single place, which will be pretty much feasible for you as well at making the developer understand things just at once. Thanks in advance
