AJAX is the art of exchanging data with a server, and updating parts of a web page without reloading the whole page. It is not a new programming language, but a new way to use existing standards. AJAX is used to make sites interactive. It can be used to create Facebook apps, picture-uploading interfaces, and much more. If you need to add functionality to an existing or new website and don\'t have the programming knowledge, our expert developers can create whatever you need.

If you are AJAX developer, Freelancer.com offers you a lot of clients who need your help with their AJAX projects which might vary from creating Facebook apps, picture uploading interfaces, and much more.

If you believe you can do that, then start bidding on AJAX projects and get paid with an average of $200 per project depending on the size and nature of your work.
