After more than 10 years of Java desktop and enterprise development, in 2003 I started to improve my knowledge about mobile applications. I wrote a book about J2ME, got Sun Certifications and then started developing for Blackberry, iOS and Android devices. In order to increase my knowledge about the Android platform I took the opportunity to write the first Italian Book about this, published in 2008. Since them I’ve also published other 5 books: the last this January about Android 6.0. In 2012 I moved to London and I worked for Telefonica, MailOnLine and Yahoo before landing to Facebook in 2015.
