About Me
I'm a Math/Computer Science student at the University of Waterloo. I grew up in Halifax, Nova Scotia.
In my free time, I write code for open-source and my own projects. Away from the keyboard, I enjoy reading, sailing, running, geocaching, travel, and learning French.
You can find me on LinkedIn, twitter, and Facebook. You can also contact me the old-fashioned way at blog@paulbutler.org. Here is my résumé.
