Hi there, I am an App development expert. I have 5+ years of experience in App Development both Android and iOS and I also have a team of expert app developers who work with me on different projects.
I have gone through your project description and have understood your task regarding project task.
I can provide for your customers having smartphones with a simple-to-use App that would allow them to choose a mode (private, business etc.). Depending on the mode, the App will then do nothing or overwrite the dialed number to place GSM outgoing calls through your platform.
I will ensure great communication throughout the project and since I will be working with my team, we will be able to work on your project keeping the strict deadline in mind. Teamwork accelerates the workflow and ensures success. I am looking forward to working with you on this project. Ping me and let's discuss. Thanks a lot.
