Additected to every new tecnologies and i have programmed everything from basic to c++ , including cobol, fortrand, pascal, lisp, prolog and of course HTML, java , php. My first program was when i was 12, i have programmed a database to manage all my games and books... in a 48k timex spectrum. So while my friends were actually trying to play games i was having fun with basic. At 18 i was doing a neural language AI application in prolog for high school. I was owner of computer companies and worked from architectural and machinery design in Autocad where i programed in Lisp to accelerate my work. My latest personal projects was the creation of a Telecom provider where i have solely developed the billing software and managed all the sites and linux servers. I am the CEO and owner of that company. So i became na expert on VoIP solutions , including asterisk where i have contributed with code changes. With that knowledge i have created and developed a new range of communication servers that today have the most advanced features i know, however having a simple , intuitive interface. Since these challenges are "done" and i need to have new projects to be happy, I am presently looking for new challenges and i have been playing with Android and its wonders. I also developed some Android applications on my own. Personally i am a workaholic. A proactive and self motivated person that in all projects i enter i give my 100%. I am a honest frontal person, i will allways contribute positivily with ideas in the projects i get involved. I am flexible and i work well under pressure, i sometimes make coworkers more nervous because i keep looking relaxed even when people are starting to panic. (this took years of training). So if you have an interesting project that is a challenge to me. I'm In!!
