I've been working with Java since 1995 when I a co-founded the first Italian magazine about this technology (http://www.mokabyte.it). After many years creating Java desktop and enterprise application, I started to work in the mobile world. In 2001 I wrote my first book about J2ME. After many J2ME and Blackberry applications, I then started to work with Android in 2008. The same year I wrote the first Italian book about Android; bestseller on Amazon.it. That was the first of a series of 12 books. I'm also the author of "Dagger By Tutorials". I worked at Yahoo, Facebook, Spotify and I'm currently a Software Engineer at WhatsApp. I'm a musical theatre lover and a supporter of the soccer team S.P.A.L.
