Hi, I'm backend developer as well as frontend. I've total 9 years experience on multiple technologies. I've been developing wide range of User Interfaces, programming backend for them, testing on users, correcting what wasn't optimal yet, testing and so on. While I know a lot of other frameworks, I'm writing mostly in Symfony, Symfony2, CodeIgniter, Zend as they are increasing my performance in the meaningful way. Of course I use CVS, SVN, Git and Mercurial (depends on a project). Of course I like scrum working system (agile). Thanks
