PHP is my preferred programming language and Drupal is my preferred framework. But I also enjoy working with Symfony, Zend and others. Actually, any open source technology is welcome. Agile methodologies and lean development have changed my life (both personal and professional). I'm a programmer and entrepreneur who really wants to contribute to make the world a better place through educational tools supported by information technology.
