Hi. Welcome. If you're new to FLOSS (Free Libre OpenSource Software), Linux, or FSF related software and wondering where to go next, email me. I'll either help or try to point you at someone who can. I've been running and using FLOSS since ca. '93 (so I should be able to help by now).
I've also done some some fairly slick (though certainly not brilliant) perl coding (my favourite environment), and I've designed and implemented a few databases (and worked with others which already existed). My writing has been published in LinuxGazettehttp://linuxgazette.net (fwiw). Since 1990, I've been a programmer, then system administrator, then independent contractor sysadmin (since '96). I like to consider myself a Kulak (self-employed peasant).
I've worked with commercial Unixes as well as the *BSD's, and quite a number of FLOSS distributions. I installed linux in Sudan (TGNBV; "The Greater Nile Business Venture") to make them legal (US sanctions compliant, so Talisman Energy wouldn't get de-listed from the stock exchange). I loved it. I didn't want to come back (and I'd love to go back).
My most recent gigs have been with ExxonMobil (1.25 a. with Midrange Engineering, refactoring a front facing security tool written in ksh which their people were afraid to touch for fear of breaking it) and a year with a small high-tech startup building a perl to MySQL interface to talk to an RFID tag reader.
Nowadays, I try to find ways to get out of North America. I'm not a social networking kind of guy, but my LinkedIn resume's mostly up to date usually|currently.
