    First i am a proud nerd. In fact, an expert nerd. 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!!

    The PHP professional you can rely on

    Canada - Last active: 04/27/2013 - Tests: 13 - Portfolio: 1

    Since 2002 I've developed dozens of applications in real estate, communication, billing, productivity, affiliate marketing and many other areas. My favorite server side technology since then is PHP, which is a very powerful tool in professional hands. I use CodeIgniter, CakePHP and love Wordpress. Dealing with LAMP stack, I've mastered Linux user and administrator skills. Finding bottlenecks and server optimization for huge load projects using VPS or cloud platforms like Rackspace or Amazon. Although I am not a graphic designer, I know my way around handling graphics, HTML and CSS. My principles are create good quality code, think ahead, be creative, foresee and prevent failures. I am seeking for the challenges to build complex web applications from the ground up. Find more on my blog http://a32.me
