I have considerable expertise in Linux, including the design and maintenance of a distribution — Zinux Linux. Zinux is based on the Linux from Scratch project, but has been greatly customized and extended for my own requirements. Most significantly, I have created an automatic build system that makes from-source installation of the entire OS a simple and speedy process. Zinux includes a complete set of standard Linux tools, a variety of Internet and network servers, and even a live CD for easy installation and emergency use.

I have also contributed patches or other code for several open-source projects including Openstack (Python), Apache Cloudstack (Java) and Salt Stack (Python) and several personal side projects including a Bitcoin exchange arbitrage trader (Golang).
