I love to solve IT problems. I teach people techie stuff. I do this mostly with open source systems. To make stuff happen I write a lot of custom scripts in various programming lanuages like Perl, Python, Bash, C, Java, Ruby, etc. I have clients all over the world (Australia, Switserland, US, etc). Occasionally I write a book, or an article for my blog.
