    PHP/MySQL Developer Specializing in E-Commerce Platforms

    United States - Last active: 1 day ago - Tests: 7

    Over the last 9 years, I have specialized in e-commerce. I got my start working on simple osCommerce installations. Since then, I have progressed to building and working with highly-customized and integrated platforms, becoming an expert in PHP/MySQL, HTACCESS, JavaScript, AJAX, jQuery, and XML. I have also had the opportunity to work extensively with many other frameworks and API's. I have a lot of experience with Google Adwords API, credit card and shipping interfaces, and numerous other external libraries. I enjoy challenge of optimizing applications for peak performance inventing new methods for automation, streamlining back-end operations, and providing custom analytics. I pride myself on being able to jump into a project quickly and to creatively solve nagging problems. Although I do have experience with HTML and CSS, I am in no way a designer. I am strictly a coder, and, simply put, I love my work. I have worked with over 140 clients on 225+ projects. Excellent communication skills and driven work ethic. I am a perfectionist, and I am not happy until the client is happy.
