    As a long-term IT professional I've had experience with almost every facet of computing. Most of my depth has been in what you might call Information Technology and Management and Information Systems, but it boils down to making hardware and software work together. I love to learn all about new systems, or old systems that are new to me, and how to keep them ticking properly. I also love to write, and have often found myself writing documentation for existing systems based on knowledge collected from a variety of people and other sources.  less
