I'm primarily a web programmer. I work with an online business administration system (accounting, invoicing, CRM, stuff) built in PHP. It does get a bit boring sometimes for every new project to still be subject to the restrictions and quirks of the same old system, but it's not so bad, and I love my workplace so I'm pretty happy. My latest big project, though I can't say much about it, is being incredibly well received and might end up being adapted by a partner company that has a huge userbase, so that's kind of cool!

Outside of regular PHP/SQL setups I've not done much other concrete programming work. I've dabbled in C++, C#, Ruby, Python, but only enough to just barely warrant mention. If I had more free time, though...

Edit: Also, I love regular expressions. I'm actually really sad that I get so few chances to legitimately use them in my job. I use them pretty much daily for find/replace operations, although those use cases are usually pretty simple.
