I've read your details very carefully and I am absolutely sure that I can do the project very well.
I have worked on projects such as by using MVC Architecture and
used laravel(view:angular), codeignitor and so on as a framework.
The projects need Chat, Multimedia Support,End-to-End Chat Encryption and so on.
I can use technologies such as HTML5 Websocket, RSA encryption and cashing .
I would love to work on your project and
wish this would be my first contract on Freelancer, and to be continued with you on your projects.
Thanks.
