See my drupal.org profile for a good idea of what I have been doing.
You can also check out my oDesk profile*.
Until recently, I maintained a list of client projects here. However, the list was always getting out of date, and it wasn’t showing my best work. I want you to see my best work, so please contact me, and I can tell you about the work I’ve done and how it relates to your requirements.
