Let's face it - a simple job title couldn't possibly describe your diverse skillset. You're known to your posse as the expert go-to guy for PHP development. You've had experience working with (or even contributing!) to open source projects like Mediawiki, Wordpress, Joomla, or Drupal.
You write awesome code, create beautiful designs, read Zeldman, think the 37signals guys are usually right (although they've got a superiority complex), understand open-source, communicate well, and hate aardvarks.
Experience with LAMP stack (Linux, Apache, mySQL, PHP)
Experience with (X)HTML & CSS
Exposure to OSS projects
Understanding of REST principles and best practices for the web
Deep understanding of astrophysics (just kidding)
