I would like to thank all my friends and the team members who work with me. I would also like to thank Rajeeva Lochana, Abhishek Saxena, James Falkner, Jorge Ferrer, Juan Fernández, and Ganesh Samarthyam for their valuable support and guidance.

A special thanks to my parents and family members for their encouragement and support during the writing of this book. I would also like to thank my lovely wife, Neha Agarwal, for supporting and encouraging me during the entire book-writing process and for her contribution in proofreading the chapters.

My sincere thanks and appreciation to the acquisition editor, Kevin Colaco; technical editor, Humera Salim Shaikh; and content development editor, Athira Laji, at Packt Publishing for their valuable support, help, and guidance. My heartfelt thanks to them for filling the communication, visualization, and technical gaps in the book. A very special thanks again to Athira Laji—without her, this book wouldn't have reached the production stage; it was really a joy to work with her.
