Acknowledgement

I still remember when my cousin Marcelo used to force me to read books when I was young. I wasn't very fond of reading in those days, and now here I am, releasing my own book. It's hard to believe that I could have achieved something that was such a distant dream for me before. So, I start by thanking you, Marcelo, for pointing me in the right direction and helping me to become who I am today.

I thought it would have been easy to write a technical book and that I wouldn't need any help. Well, I've proven again that we can't conquer anything alone. I've had the pleasure of having four friends help me by reviewing this book. I can say now that I could not have finished it as I did, without their help. So, thank you Alessandro, Carsten, Kristian, and Vinícius, for all the time spent reviewing, with such perfection, the chapters in what I call "our" book.

I would also like to thank all of those on the Packt team involved in this project, who helped me right through; first, Stephanie, who was my first contact, and then later, Azhar, Brandt, Joel, and Pooja. Thank you, guys.

And last but not least, my wife, Juliana, and my son, Eduardo. I am very proud to have had your support right since the beginning; you even gave up the time I could've been spending with you so I could write this book. I dedicate it to you with all my heart.
