I take this opportunity to express my deep gratitude to my parents, Abdul Majeed and Safiya; my wife, Ameena Rahamath; and my daughter, Nyla, for their unwavering support and prayers in every phase of my life and growth.

I would be remiss if I do not thank my friends for their constant help in both the personal and professional spheres. I am truly blessed to have worked with some of the smartest and most dedicated people at Appfabs. This humble endeavor would not have reached fruition without the motivation from my dear colleagues, especially Mariya John. Also imperative to this journey were Devika Battike and Shrileka Inani, my editors at Packt—thank you for pushing my limits.

And finally, to God Almighty, for making all of the above possible.
