Leo has been around forever. He has seen everything, done everything. Over the years, Leo has been working as a developer, as a project lead, as a tester, as an analyst, as a manager, and as a consultant. He knows from experience that everything comes back, if you only wait a few years. He has learned that the same problems and the same solutions have been invented and re-invented a hundred times in computer science. He has lived through the rise and fall of uncountable new technologies and methodogies. All of them brand new, all of them the one and only forever best way to make software. Leo wants to go to XP Days because he thinks it's an excellent opportunity to meet with a lot of young, smart and enthusiastic people.
