About us

At Extrema Sistemas we do IT consulting and training. As Certified Training Partner by Google and Pivotal in Spain and Italy, we deliver all the official training courses for Google Cloud and Spring.

We have developed the software for strategic projects for airports, naval traffic management, banks and logistics companies. In 2012 we started organizing Codemotion Spain, the biggest IT event in the country dedicated to software developers.

We are a small and dynamic company, where every member of the team works from a different location.
