Hey! I'm Nazareno, a 25 years old web developer from Buenos Aires, Argentina living in Amsterdam. I started programming in my spare time when I was 12 years old in PHP+MySQL+JS and I didn’t stop learning since then.

Frequently I give talks and seminars about PHP, Web Security, MVC Frameworks and other topics in events and institutes. (PHPDay, EducacionIT, BarCamp, etc.)
