Web Designer, Template Hacker and occasionally do a few plugin enhancements. Most of my work is done in WordPress and Joomla. I have done a few sites outside of those two platforms. (vBulliten, phpBB, magneto, and a few others) I was a hardcore Joomla supporter until a really jumped into WP with both feet. I do like the directory structure and the ease of making truly custom templates. Child themes is also a great option not available through other platforms.

IMHO Joomla still has a couple things I wish we could see in WP –
1. Super Admin Role
2. In WP everything is a plugin. Seems that should be separated like in Joomla into Components for major site functionality, plugins for things like lightboxes (additions to existing functionality), and modules… this is pretty much widgets in WP.
