Software architect and developer. I use a variety of technologies but at work it's generally C++, HTML, ASP (JScript), Flex, and SVG. For personal stuff, I tend to use PHP, C#, perl, and everything I use at work. :)

I've been designing and developing for well over a decade in the enterprise software market, first with IP billing, now with ticketing (no, not TicketMaster). I'm a classic case of a jack-of-all-trades, but my intuition is good and I pick up programming languages like a sponge picks up water.

For fun, I'm an avid amateur photographer and especially enjoy nature and macro photography. I've also started getting into more studio oriented stuff, acquiring some lighting, background stands, and other gadgets for that purpose. My current weapon of choice is the Nikon D800. Check out my website for some of my photography DIY projects, some of which have been featured on the well-known DIY Photography site.
