I want to dedicate this book to two women in my life—my mom and my wife.

To my mom, Thankamani, who sacrificed her entire life for me and struggled to make my life smooth. She worked hard without even noticing that her health was failing, in order to make a good living for us. She showered us with love, and she taught me what life is. She passed her strength on to me so that I could achieve my goals.

And to my wife, Vaidehi, who has always believed in what I do, who supported me in my bad days, and whom I believe as my soul. She taught me how to be calm when I am disturbed. She taught me what unconditional love is. She spent her time transforming me into a better person.

Dev, my son, my joy, my pride, my blessing, my love. He gives me an immense amount of happiness when I look at him.

My father, Venu, who played an amazing role in my life and in making me the person I am today.

My sisters, Sini, and Siji, for having faith in me. A sister is an angel on earth who brings out your best qualities, I am lucky to have you both. My brothers-in-law, Sumesh, Shaiju, and Vaitheesh, for standing with me all the time, no matter what the circumstances were.

My father-in-law, Ramakrishnan, and my mother-in-law, Usha, for giving me continuous support all the time. Thank you for never letting the words “in-law” get in between our relationship. You are the best in-laws in the world.

Ajaybhasy, my friend, without whom I would have not selected this profession. He has been the one true friend with whom I can share anything.

I also want to dedicate this book to all my relatives, friends, and followers. Without them I would not be where I am today.

A debt of gratitude to Jessica Vakilil for her continuous support in editing this book to the state what you have now, to Aaron Black for his initial support and for selecting me to write this book, and to everyone at Apress for their belief in me and in this project.

And last, but certainly not least, you, the reader. Thank you for your support.
