I have been a developer for too many years, ok around 30, and have done a lot of different things. The skills I listed are what I am most familiar with - I'm currently doing mostly C# on both the desktop and compact .NET frameworks. I do a lot of wireless programming, in terms of querying and setting up the wifi adapters, but not much at the packet level (though am not averse to doing that). I can switch pretty easily between C#, C and C++, and also Windows and Unix (LINUX and others) operating systems.
I pride myself on good object-oriented designs and attention to detail. I enjoy solving problems; two cases in point: After Oracle had looked at a problem for about 6 months that Xerox was having, they called me to see if I could help. After 3 days they were up and running - ok, that took a bit of luck but I've heard people say that we make our own luck. Another time a group of developers had to design and build an entire asp-based web system for a major power company in Pen
