I would like to take a moment to thank everyone that has been a huge support during the course of writing this book. Firstly, thanks to Mr. Raghu Potini, who motivated me to write this book and has been supportive throughout the writing process. Without his support and motivation, this book would have not been possible. Secondly, I would like to thank Mr. Andrew Leasck, who has been my inspiration since the beginning of my career. When I started writing the book, I did not know much about the publishing process or the amount of team work it needs. While working with the Packt Publishing team, they made me realize that it requires enormous amount of team effort, coordination and patience. The Packt Publishing team made it look so simple, but behind the scenes, they put so much effort and thoughts into giving life to this book. Without them, this would have not been possible. Hats off to the Packt team members that helped me during this process. Everyone has a role model in life. My father has always been my role model and an inspiration. Thanks to my father, Mr. Murugesan, who would have been really proud about this book. Special thanks to my mother, Vijayarani, wife, Subamalar, and daughther, Sreesha, who have been very patient and supportive during the course of writing this book.
