Developer always eager to learn and improve. I work as Android developer at Liferay and I’ve worked in many development stacks: JS (angular, node…), Java EE, Scala or python. I love challenges and learning about data visualisation. I am an organizer in @cylicon_valley, a tech meetup in Spain, to help spread better technical practices in other companies and a member of the board of @agilespain, the Spanish Agile national association.


A smiling introvert with a chronic curiosity. Working as a business analyst for the past 4 years only made it worse. :) But it has proven to be a great way to hang around with other geeks. When not in the office, Mateja can be found running or cycling in the mountains.


Roko has been coding in Java since 1999. Nowadays he is not focusing on coding and this fact is making him even more sad as time goes by. He was dragged over to the dark side as he mostly manages stuff now. Roko is an author of the first book in Croatia on Agile and Lean methods. He helps run a local Java Zagreb meetup group. He codes from time to time, hoping that the force will be strong with him again one day. A passionate rock climber.
