Mostly-Ruby Developer, >20 years experience

Ruby since 2004, rails since 2005, c++ since 1995, html & css since 3.2. Linux since 1996. After that much practice, I'd be surprised if I wasn't good at code'n'data. I make bread, play squash, Go, guitar and fretless bass, ride offroad motorcycles, and most importantly raise kids and be a husband. Consequently I have lots of practice at listening and helping. I love the way a person's eyes light up when they get an aha moment.

Freelance Jruby developer in Alma, United States

Founder of Unicorn.TV

I'm a classic hacker, and not in the "I dabble in tech stuff" way. I've been programming in low level languages for since 2000. My passion lies in teaching others. In the hacker world, there are often Master:Apprentice relationships, but this is a more rare concept in traditional CS/engineering; which is unfortunate. When it comes to work and life, I am very passion driven. I don't take on just any project, but when I do it is with a great amount of energy, loyalty and dedication to quality.
