I have a degree in Mathematics by the University of Barcelona. Have worked in a few things ranging from a small music shop to proofreading math textbooks for six years. I have been into computers since I was a kid, programming has always been a passion, and switched to being a programmer for a living after doing one year of PhD.

I spend most of my spare time contributing to open source. Open source is all about knowledge sharing and collaboration, principles I strongly believe construct a better society.

I have been around Ruby on Rails since 2005. I am a member of the Rails core team, and the author of Rails Contributors. Also honored to have been presented a Ruby Hero Award in RailsConf 2010, and to be part of the team who organised the European Ruby Conference 2009 (EuRuKo 2009), held in Barcelona.

I was also into Perl for some years. I am a CPAN author, and former leader of Barcelona.pm. Back in 2006 I published an article about the intricacies of newlines for O'Reilly's ONLamp.com. Also taught a Perl semester for seven years at the University of Barcelona as a part-time lecturer. That was vocational, I did it in my spare time.


Reading is one of my passions. I keep a listing of the books I read.
