Acknowledgement

This book is dedicated to the loving memory of my mother, Smt. Sumathy; without her never-failing encouragement and everlasting love I would have never been half as good.

First and foremost, I have to thank my father, Sri. Prabhakar Pasupuleti, who never ceases to be a constant source of inspiration, a ray of hope, humility and strength, and whose support and guidance have given me the courage to chase my dreams.

I should also express my deep sense of gratitude to each of my family members, Sushma, Sresht, and Samvruth, who stood by me at every moment through very tough times and enabled me to complete this book.

I would like to sincerely thank all my teachers who were instrumental in shaping me. Among them, I would like to thank Usha Madam, Vittal Rao Sir, Gopal Krishna Sir, and Brindavan Sir for their stellar role in improving me.

I would also like to thank all my friends for their understanding in many ways. Their friendship makes my life a wonderful experience. I cannot list all the names here, but you are always on my mind.

Special thanks to the team at Packt for their contribution to this book.
