Hi,dear
I am a proficient mobile developer. I have been developing for 6 years.
I developed 54 social networking apps, so I have got lots of experience.
Chatting app was already experienced with me and you can see it on my portfolio.
I am also a web backend developer, so I can make the backend which controls contents.
So I can make your project easily and perfectly.
If you provide project's detail, I can make design of your app , implement the design by coding, submit it to the App Store.
I can make your project within 5 days.
I'll look forward to your response.
