The client version will be built for iOS and Android for now but later maybe expand to other platforms. The app involves photo sharing and chat system.

Prior experience in building data-driven applications and API would be preferable. Please share some your previous work and let me know why you are suitable for this particular task. I am not interested in reading copied messages!

Finally, please write in your message - how much you will charge if I wanted to hire you for 1 to 3 months.
