First of all, I would like to thank Lord Krishna for inspiring me at every movement. You have given me the power to believe in my passion and pursue my dreams. I could have never done this without the faith I have in you, the Almighty.

I would like to take this opportunity to thank the team at Packt Publishing for all of their outstanding work in helping to bring this book to fruition. They were very supportive and their processes are designed to improve the quality of the book. I have thoroughly enjoyed working with them throughout the entire process, and appreciate their candid feedback, which ultimately raised the standard of my work. I would like to give a big thank you to the reviewer, Devin Weaver, whose constructive criticisms and observations have also served to raise the standard of the final product.

I would also like to say thanks to Rakesh Gupta, AVP of Engineering, Impetus, for his continuous support and for encouraging me to write this book.

Finally, I would like to say thanks to my wife, Sweeni Sethi, and my kids, Pranjali and Punya, for their never-ending support, which keeps me going.

I would like to thank my mother, Sudesh Sethi, and father, Jagdish Lal Sethi, for giving me constant morale throughout my life.
