Cavan Donohoe - Data Scientist
Welcome to my Website! It’s all done in R and GitHub, so that’s pretty cool. Most of the data updates itself on a schedule too.
I thought it might be worth investing some time to make a website to point to an area of my life where it gets a little more professional. But then I thought, why just do that? Why not incorporate some other aspects of my life that makes me me. So yes, this will have my ever growing resume, but let’s have a little bit of fun while we’re here.
