I'm a Sophomore college student at Clarkson University in Potsdam, NY. I've been doing web development for pay for around 3 years now (before that it was a hobby). I've worked on a lot of small business websites as well as a few larger ones. I don't maintain a portfolio (I'll get to it at some point), but I can point you to pertinent stuff I've done if you'd like.
