At the time of writing this book, I was fortunate to work with an excellent team at Packt, whose contributions vastly improved the presentation of this book. I would like to thank my technical reviewers, proofreaders, and my colleagues for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained over their many years in the software development industry. This book was possible because they provided valuable feedback. The entire process of writing a book requires a huge number of lonely hours.   I would like to thank my wife, Sunanda, and my son, for their patience and endless support.
