about me

Let me tell you a little bit about myself. My name is JC Tierney, and I was born and raised in the suburbs of Chicago, IL. I am a life-long Blackhawks, White Sox and Bears fan.
I graduated from Benet Academy in Lisle, IL in May, 1996. After highschool I attened the University of Dayton for 5 years, and graduated in May, 2001. I graduated with a degree in Management Information Systems, and I loved every minute of my experience.
Currently I am employed as a software engineer for Bitly in Denver, CO. This website was created mostly as a way for me to have my own email address (jc@modnar.net), but I decided I might as well publish some content as well.
