I’m a Ruby developer from Helsinki, Finland. You can find me and my open source projects on GitHub as matiaskorhonen, I occasionally blog about programming and a variety of random things at randomerrata.com, and I tweet as @matiaskorhonen.

I’m also an amateur photographer. If I manage to take a decent photograph, you might find it either on 500px or on Flickr.

My latest endeavour is a book price comparison site called Piranhas.
