I've got 4 years experience with PHP and MySQL and have been comfortable with AJAX for a half year now. I can do XHTML/CSS designs (coding), but it isn't my first choice. I've worked on various projects including user systems, content management systems, realtime payment processing & site response systems, and various statistics.
My ideal project is relatively small (on the order of a few weeks - a month or two), but can be any degree of difficulty. I welcome new challenges that force me to learn, but enjoy doing the same old.
