    Linux server administrator

    United States - Last active: 04/30/2011 - Tests: 3

    I possess a broad range of skills, everything from security best principals and practices, to network troubleshooting and server administration. My server administration experience mainly revolves around Linux and UNix platforms, due to their overall accessibility and command-line nature. While I happen to enjoy some programming, my main professional strengths lie within the administration areas. That is not to say that I have never programmed at all professionally; in fact, my last job had me doing a lot of coding in PHP5, with some Bash and Perl scripting thrown in for good measure. If you have any further questions regarding my skills and or experience, please do not hesitate to ask!
