I've been working with UNIX, GNU, and Linux for over 25 years. I've done significant programming in over 40 programming and scripting languages, including Smalltalk, Objective-C, C, Csh, bash, perl, awk, m4, puppet, ansible, hadoop, whatever.
I've worked as a consultant, systems administrator, customer support representative, project manager, trainer, founder/CTO, DevOps duty engineer, DevOps advisor, and button pusher.
For fun I play guitar (acoustic and electric), build LEGO robots, tweak http://reiber.org and make random contributions all over the internet - see: http://bit.ly/reiber which just scratches the surface.
