    Let me introduce myself, my name is Luis Alvaro R. Gonzalez - from the Philippines. I have a Bachelor's Degree in Marketing from the University of the Immaculate Conception. Yes, I studied Marketing, but I also have a strong passion for computers and the Internet. When I was in college, I worked nights in an Internet cafe and started taking programming projects for computer science students to earn that extra cash to buy myself a computer. I am currently working for a technical consulting company as an independent contractor. I handle clients' server/network issues as well as develop custom desktop applications. I also champion all of our clients' Exchange server migrations from Exchange 2003/2007 to Exchange 2010. I am also now studying Windows server 2012 as well as exchange 2013 in preparation for upcoming migration projects.  less
