    I have always been passionate about IT and the infinity of possibilities it gives us. I belief the only limitation is how far imagination can go. So I am really eager to learn any new and cutting edge technology. Over the last years I have worked on different projects developing software, administrating servers and network services from basic network services to virtualization, firewall solutions, VoIP servers. I also have a good security background. I also have good web administration and development background as I implemented phpBB, Joomla and Drupal platforms. And I don't using some basic graphics skills when needed. My career objective is to lead a big innovating IT project and work with a great engineering team. And my long term objective is to start my own IT company. I always do my best when working on IT projects, so make sure your project is in good hands.  less
