Windows / Linux / Unix sysadmin since '96. Cut my teeth on Xenix (ick!) and have been a Linux user since '93 (yay-- Slackware!). Worked w/ more Windows NT 3.51 and 4.0 than I care to recall. Today MSFT stuff mainly pays my bills but I try to keep at least passingly familiar with Linux.
I've been an independent consultant / contractor since 2004. I write some code too but my main gig is sysadmin and IT project work.
