I would like to thank Packt Publishing for the opportunity they gave me to write this book. This has been my first time as a writer and, for sure, it has been a challenging task, but their support has been constant and fundamental in making it possible. I would like to thank my colleague Duncan Moles and my old friend Emanuele "Lele" Rabino for accepting to review my first drafts. Their helpful advice comes from their skills and expertise. My gratitude goes also to Jean-Luc Marbot, Roberto Forno, Atif Aziz, and Gustavo Perez Leon. I learned so much from them in the last couple of years, and they have been very important to me during my adventure in Switzerland.

My biggest thanks go to my intercontinental family, without whom this book would not have been possible: my parents and brother in Italy, who have always supported and loved me; and my adoptive family in Paraguay, who received me as if I had always been one of them. And, of course I would like to thank my wife, Cecilia, who's at the center of my life: I love you.
