Hi! I'm Roberto. I'm a Brazilian Engineering student at the University of São Paulo and the Ecole Centrale de Lille (France).

I've participated in the Imagine Cup competition and went to the world finals every year from 2005 to 2009. I also won the 1st place award in 2006, in India, for the Interface Design invitational, in 2007 in Korea, for the Embedded Development invitational, and in 2009 in Egypt for the Windows Mobile Award.

Currently I keep a blog (in English and Portuguese) at http://virtualdreams.com.br/blog/ and a weekly webcast about WPF and Silverlight (in Portuguese) at http://www.xamlcast.net.
