    Web Developer Java/GWT/JSF Python/Django, PHP/MySQL

    Colombia - Last active: 03/22/2013 - Tests: 1

    When even was in school, I was fortunate to be good in areas that were difficult for others. He loved math and physics but did not know exactly why. At that moment I had something very clear, I do not want to work behind a boring desk doing paperwork every day. I liked a lot of video games I had installed on the computer and discovered a couple of interesting things about them, so I thought, "If I study related careers with computers, I learn many more interesting tricks." I chose to study systems engineering with the wrong idea, but I found something much more interesting. To succeed it was necessary to read (a lot), learn, share, discuss, and implement. She loved him. For some economic problems, I became a programming teacher of some classmates, so I learned a lot. Since then, and after overcoming many difficulties, I have become a developer, with the programming to continue learning and meeting interesting people. Currently developing applications on Python, Java and PHP (or any other open technology) and I'm learning about Android and new development paradigms.
