First of all, I would like to thank Steve Jobs for being my inspiration and motivation throughout. Selling something that a person does not need at a fancy price is not an easy job. He has done this time and again, right from Mac books to Apple watches. R.I.P, Mr. Jobs.

I don't think a simple thank you would suffice in appreciating what my family has done for me, especially my mother. They have always been there for me through good and bad times, sharing my happiness and encouraging me whenever I was down. I could not have made it so far without their help and support.

I would like to send out a special thank you to Nicholas Gault and Andrew Nuss for all the learning, support, and encouragement that they have provided me so far.

I would like to thank Udaykanth Rapeti for preaching me these golden words: "create a digital presence if you want to really succeed" and for always being there for me. A special thanks to Karthik Naidu, Pavan Musti, and the gang I worked with at Deloitte. The times could not have been better!

I would like to thank Ali Baig, the self-proclaimed yoda, for all the advice and ideas he keeps sharing with me. Keep them coming! A big shout out to the fresher batch at Accenture and the Cactus gang. I cherish each moment I spent with you guys, learning, playing, and rocking! Go Cactus, go!

I would like to take a moment to thank my first love. You have taught me a lot of things and made me a better person. Our breakup was one of the motivations to keep myself busy in technology, which definitely added to where I am today. Thank you so much for everything.

Writing nine chapters and an appendix is a humongous task. Imagine editing and reviewing the same. My sincere thanks to Merwyn D'souza, the content development editor of the book, and the reviewers, Bramus Van Damme, Ian Pridham, and Indermohan Singh. This book is in a lot better shape because of you guys. I am honored to have worked with Shashank Desai, the technical editor of this book. I am very happy that this is his last book before he moves on as a project manager. Congrats! Also, thanks to Nikhil Nair and everyone from the Packt Publishing team for making this possible.

A special shout out to Hemal Desai for finding me and getting me on board to write this book. This book wouldn't have happened without her.

A big thumbs up to my blog readers. You guys rock!

Last but not least, my respect to the Robin Hoods of the developer community, who develop and share free code!
