Roberto Cortez

Speaker 2014

Freelancer, Speaker, RebelLabs Author, Blogger, Passionate Developer

My name is Roberto Cortez and I was born in Venezuela, but I have spent most of my life in Coimbra – Portugal, where I currently live. I am a professional Java Developer working in the software development industry, with more than 8 years of experience in business areas like Finance, Insurance and Government. I work with many Java based technologies like JavaEE, Spring, Hibernate, GWT, JBoss AS and Maven just to name a few, always relying on my favorite IDE: IntelliJ IDEA.

Most recently, I became a Freelancer / Independent Contractor. My new position is making me travel around the world (an old dream) to customers, but also to attend Java conferences. The direct contact with the Java community made me want to become an active member in the community itself. For that reason, I have created the Coimbra Java User Group, started to contribute to Open Source on Github and launched my own blog (, so I can share some of the knowledge that I gained over the years.
