I've developed web applications making extensive use of AJAX and web technologies: HTML, CSS, jQuery, PHP, MySQL. I've used frameworks, plugins and tools such as: CodeIgniter, jqGrid, SMARTY
I also have experience developing desktop applications using C++, C# and Java
I look forward to creating your (web) application for it to be a success.
