I love technology and learning new languages, frameworks and platforms. I've been an I.T. professional for 25 years and was a computer enthusiast/programmer before I made it a career. I have worked as a consultant on many large & complex projects at Fortune 500 companies. Although my experience has been large corporate systems (ERP, e.g. Oracle PeopleSoft), I have found that I want to be more involved in startup projects using modern tools and techniques. To keep current with technology trends, I often work on side projects, some of which never see the light of day and others that have a significant user base on the public web.
