Javier travelled to Barcelona to specialise in mobile design, learning UX for apps since the first versions of iOS and Android. All his experience was put into 'Designing Mobile Apps' a book he co-wrote with José Vittone.

The repercussions of this project took him to make part of different design events and conferences around the world, such as Colombia 3.0, UX Spain, UX Sofia and Campus Party (Ecuador and Brazil) among others.
Javier has taught design at ELISAVA and IED, the two most well- known design schools in Barcelona. Besides this, he has held and co-organised design workshops in more than 15 countries around the world, from Cuba to China.

Finally, if you are curious on learning more about how Javier thinks about design, you can read some of the articles he has published on Smashing Magazine. (The other option would be to invite him for a coffee or beer, that he'll gladly accept!).
