Javier is a polyglot programmer well-versed in Ruby, JavaScript, Objective-C, CSS & HTML; as well a self-taught illustrator & designer. He also happens to be one of the first persons to start a blog in Spain... but that's another story.

Before becoming part of the Vizzuality troupe, he enjoyed one year of freelance working and crazy biking in the rainy city of Amsterdam, doing illustrations for several Dutch companies and mobile apps in the Goodfellas Network's headquarters.
