I want to create useful things for useful people, and in doing so help useful people become more useful.


If you're looking for all the buzz words, I'm probably not the right candidate for you. I specialize in learning what I need to know to solve the problem at hand.

That said, if you need the buzz words, here's a few.

  • Operating Systems: Ubuntu/Debian, CentOS, Redhat, etc.
  • Languages: Ruby, Golang, JavaScript (Node.js and client), Python, etc.
  • Applications/Tools: Docker, Git, Nginx, etc., etc., etc.
  • Development Processes: Agile/Scrum

Experience - Open Source (a.k.a Nights and Weekends)

Over the last few years, I've worked quite actively on several open source projects, some by contract and some just for fun. Aside from the highlighted projects below, have a ton of stuff on Github, as I use it as a bit of a scratch directory. For highlights and additional information on some of the other projects (gem's, npm's, etc.) I've created, see:


BootstrapCDN is an open source web site, focused on easily and reliabily deliever Bootstrap client design framework to the public in a free and open source capacity. I work closely with the developers of Bootstrap, Font Awesome and Bootswatch, delivering updates and site enhancements as necessary.

Httperf Tools

Httperf is an open source C based performance testing tool. No I didn't write it. I do however maintain a fork and have written bindings and tools for it in several difference languages – see: httperf.js, httperf.rb, and a few others on my Github.

MaxCDN Tools

I have written and maintain several libraries and tools for integration with MaxCDN's OAuth API. This includes MaxCLI (a suite of Golang based cross platform commandline utilies) and libraries for Ruby, Python, Node.js and Golang.
