I would like to express my deepest appreciation and special gratitude to all those from the Packt Editorial team who helped me complete this book, especially Francis Savio Carneiro, Larissa Pinto, and Diksha Wakode.

I'd also like to thank Adrian Aguirre and Tony Guerrero for all the help in the book. Finally, my deepest thanks to my wife, Cristina Rojas, for the support; my parents, Francisco Santana and Thelma Roldan, who have supported me in my professional growth; and my friends and family who helped manifest the book.
