Acknowledgement

There are a few people I want to thank for the continued and ongoing support they have given me during the writing of this book. First and foremost, I would like to thank my family, who educated me, taught me how to be independent and strong. Leonardo Mendes, who was the technical reviewer of this book and is one of my best friends. Gabriela Dias, who was the best leader that I had in these ten years of experience in IT and is a great example of a person for me. Juergen Bohn, the boss who brings me to Germany and opened so many doors and uncountable opportunities in Europe. I could have never completed this book without these people in my life.

This book wouldn’t have happened if I hadn’t had the support from BPB Publications, which gave me the support and attention while I was writing.

Finally, I would like to thank God who gave me the intelligence, strength and all the ways for me to be where I am right now.
