PHP, MySQL, OsCommerce, Ajax and Js libs (jQuery and Prototype) - these are my primary (but not only) tools that I use every day. I am always trying to become better than I was a second ago. New technologies and knowledges are my morning breakfast and that is why it's usualy easy for me to get on any new things in web development (note: I learn offline). I have strong object-oriented programming level with php5. Use MVC and other OO patterns. Hard separation code from templates and data. I use very powerful framework onPhp (it similar to Zend, Symphony ).
