Below is a list of skills which I have some degree of expertise in.  I have listed them in a way to show how recent my experience with each skill is and roughly how many years I have had using them in a professional capacity.  There are a number of programming languages that I have played with, but I haven't listed them here since I haven't really used them outside of a theoretical sense.  This list is ever expanding and quite honestly, there are platforms and languages that I have used and simply forget about them.  I add them when I think about them and try and keep the list somewhat up to date.  If you have a requirement for specific skills, you should email and ask me about it and I can tell you pretty quickly whether or not I can help you with it.
