My Story

I have had a passion for app development and computer science ever since a young age. I began programming in middle school and continued to develop my skills throughout high school. I am now attending Indiana University to study computer science. In my free time I develop iOS and WatchOS apps, as well as contract development work for various companies.

When I am not programming I snowboard, wakeboard and work on my car.
