I have an experience of 20 years in the information technologies. I started as a 4gl, embedded sql + c, c developer for 2 years. Then I was a sybase consultant and teacher for almost 4 years. Then I was a sun microsystems consultant (java center, enterprise consulting, access management) for 10 years. Since 2009 I am a freelance consultant and I focus on java developments and everything that has something to do with the technology in general. I have switched from OpenSolaris to Ubuntu since January 2012. I like very much Ubuntu and everything it has to bring to me as a professional developer.
