I have been developing database driven websites for many years now, created plugins for a variety of CMS's and worked with a several API's.
I enjoy looking into the security side of things as well, examining the weak points of sites and servers. I've found it really does get overlooked.
I am now working on a CMS system in which I was the key developer, Coaster CMS. The main focus was quick website development and a simple use interface.
