I was born in Buenos Aires, capital city of Argentina, in 1967. When I was at the University of Buenos Aires, studying for Electronic Engineer, I became in one of the 11 guys envolved with the development of an Computer Center for students in the Computer Dept. of the University. I was only 19 years old, so the challenge was amazing. One year later, I also begun to teach in several disciplines, all of them related with programming. After those 4 years, I went out of the University looking for more challenges, starting as a Systems Supervisor in a medical company, up to now, being a Technology Manager. I really love challenges, so if you have one, please let me know !
