I'd like to express my deep gratitude to my parents for supporting me in my journey through computers since I was 8. To Urszula, Tyrion and Tesla for their daily support and for being with me in the long nights writing this book.
I'd like to thank Chaitanya, for her guidance at the beginning of the book, Zeeyan, for his patience and help on every chapter, and Pavan, for the help and explanations. But also to all the reviewers, especially to Shiju, and the entire team at Packt that made this book possible.
