Preferences: If you go for the personality type thing, I am closest to INTJ and ISTP.

I enjoy solving problems, especially challenging problems, especially ones that require optimization of various metrics. These challenges present themselves through many forms in our lives. If a challenge seems to be over my head, I perform the necessary research to learn and become familiar with the various technologies and theories in the problem domain. I then apply my own analysis to the problem to work out a nice solution.
