I'm a developer, web standards advocate, and version control guru. Most of the windows on my screen are black boxes with white text.
I currently work for TDS Telecom. Their opinions are theirs, mine are mine. This page contains my opinions, not theirs. Previous employers have been: state government, a startup, a telecom company, a production house, a nonprofit, and a university.
I can write code productively in Python, Ruby, or Java, preferring Python as my choice for a new project. I'm slightly less efficient in PHP, Perl, or C++, having lost the day-to-day knowledge. Any other language, I can puzzle out and make modifications to existing code, but would take a week or so to get up to speed. Programming is programming, no matter the language. The differences are just idiom.
I can and do install and maintain linux on the desktop or as a server. I prefer Debian. I've been responsible for installing and maintaining web servers, database servers, email servers, version control repositories, jabber servers, file servers, and continuous integration servers.
