Hii,
I am a Mobile Application Developer, with over 5-year experience dealing with the latest variations of Android and IOS technology.
I can develop & build this application with proper datastructure over secure data transmission through API calls as well as cloud storage too.
I can generally take a short period of the timeline to complete this project based on the overall requirement provided by you. I'm interested to hear more about this project and about the beginning-to-end workflow. If you award me the project I'd be very happy to discuss this further and get started for you as soon as possible.
Thanks!
