I've 9 years of experience in website and web application development.
I work in PHP, MySql, jQuery, javascript, CSS. I've developed websites, web applications, CRM, CMS. I also do web designs using html & CSS. If given PSD, then I also convert them into HTML. I can do responsive websites, and cross-browser compartible websites.
I can change an existing website's look and feel to make it better.
I can implement jQuery/AJAX based popup to the new/existing websites.
