First and foremost, I would like to thank my wife, Gurpreet, for her love, encouragement, and extreme patience during the book writing process, which mostly occurred on vacations, weekends, and overnights. I dedicate this book to my parents and brother; without their support, this book wouldn't have been possible.

I wish to extend my special thanks to Amit Dubey for his guidance and directions, which always proved helpful. I would like to express my gratitude to Vijay Sharma. I learned ways to handle complex problems with a simple approach from him. I am highly grateful to Saurav Bhattacharya, Mohit Sindwani, and Tarun Nigam for being highly supportive during the course of this book. I am also very thankful to Dr. Ulrich Kabatek for providing me flexible timings, which helped me finalize this title.

I acknowledge the contribution of the entire Packt Publishing team and external reviewers. Their constant feedback and constructive comments have helped me take this book to another level. I am grateful to James Jones and Harshal Ved for their support on this title. A big thanks to Shashank Desai, whose coordination helped us meet the deadlines on time. I would also like to thank Athira Laji who has done a remarkable job over the year to bring the best out of this title. Her constant motivation, tracking deliverables, self-correction, and review comments has contributed a lot to this title.

I would like to express my gratitude to Shraddha Parganiha, Neeraj Sahu, and my close friends, Nidhi Pasricha, Jitendra Verma, and Rubina Hasrat, for their help and support during the time when I needed them the most.

Last but not least, I would like to say thanks to the "Gang of four"—Abhinav Singhal, Nisha Dawar, Smitha Nair, and myself—for all the happy moments we shared together. Cheers!
