I have to develop a Chat App on mobile phones. For that, a PHP experts are required who can do customization on my already developed Backend (in php).
I also have a Chat Server in cake php. My mobile developer requires customization on Chat Server and to provide the API's to him that allows him to use chat server to flow messages back n forth and to save it to my db in sql.
Chat Server code will be provided and that needs to be integrated to my backend server as well.
Also two API's for backend service are already coded (One is Login, 2nd is pulling friends list from db). It simply needs to be hosted / integrated to my backend server. the code will be provided.
There could be 2-4 new service API's to create on my backend. for e.g, registration data send through mobile client, or some other data send to my backend db and response required from db... etc etc
Third thing is customization requried on a sign up page of my website. There are two fields "email" and "mobile" that are mandatory. We will simply put an "Or" in between and make it optional. Also during the time of registration, verification code is send to email as well as SMS to mobile because both fields needs to be entered. The user is however, authenticated at first time login , via verification code of the Mobile only... email verfiication code, doesnt authenticate yet... so we will keep it flexible for both... even if a user enters verification code of his email .. that will be accepted as well..
Budget: US$ 200 Only.
I will create easy 3-4 milestones of 50$ each to make it easy to do it...
There is no specific time limit because mobile development is taking place simultaneously and is time consuming.. there requirement is basically to be implemented so we will have to wait for their customization requirement, implement it , than they will create the client, test it and so on ...
