I dedicate this book to my beloved grandfather who is the prime reason behind whatever I am today. He is my source of inspiration and he is the one I want to be like. Not a single line of this book was written without thinking about him; may you stay strong and healthy.

I want to acknowledge the support of my family, especially my parents and siblings. My conversations with them were the power source, which kept me going.

I want to acknowledge the guidance and support of my friends for insisting that I should do this when I was skeptical about taking this up. I would like to thank Ajit and Pranav for being the best friends one could ask for and always being there for me. A special mention to Vijayaraghavan for lending his garden for me to work in and relax post the long writing sessions. I would like to thank my college friends, especially my wing mates, Zenithers, who have always been pillars of support. My friends at the Young India Fellowship have made me evolve as a person and I am grateful to all of them.

I would like to extend my sincere gratitude to my faculty and well wishers at IIT Madras and the Young India Fellowship. The Tiger Analytics family, especially Pradeep, provided a conducive environment and encouraged me to take up and complete this task. I would also like to convey my sincere regards to Zeena Johar for believing in me and giving me the best learning and working opportunities, which were more than what I could have asked for in my first job.

I want to thank my editors Nikhil, Amey, Saurabh, Indrajit, and reviewer, Matt, for their wonderful comments and prompt responses. I would like to thank the entire PACKT publication team that was involved with ISBN B01782.
