    I have been building web applications for over 7 years now. I have a deep background in fundamental PHP5 (with MVC architecture), MySQL, HTML5, CSS3 and jQuery. I am currently focused on Laravel and Wordpress web application work, including building plugins and creating responsive design sites. My previous expertise includes Codeigniter, Yii framework, AJAX, PL/SQL, Oracle DB and Java. Even though I have no proven track record in developing Zend 2 - and Kohana-based sites, I am ready to deal with such projects as well. Regardless of the programming, I am passionate about providing first class results and excellent service. I love presenting the solution I feel is best for my clients and work with them to get them what they need. I am looking for interesting full-time, and ideally long-term projects to keep busy.
