Firstly, I would like to thank my two managers at Apollo America, Peter Stouffer and Louise Laing, for giving me a very flexible schedule to write this book, without which I would have never been able to write it in a reasonable amount of time. Secondly, I would like to thank Riddhi Tuljapurkar, who was my content editor and my contact at Packt Publishing for this book, for being flexible when it came to chapter deadlines as well as for giving me good feedback on the chapters. I would also like to thank Llewellyn Rozario for giving me the opportunity to write this book in the first place. Finally, I would like to thank the five technical reviewers, Ayun Park, Ben Chaimberg, Nidal Alhariri, Rotem Yaari, and Pedro Baumann, for investing their time and energy to make the final product a whole lot better than the initial drafts.
