I would like to thank my other half, Claudia ATK, for her sleepless nights and the positive vibes she shared with me throughout the writing of this book, as well as Brigitte and Franois, my parents, for whom I have a lot of love and to whom I dedicate this book entirely.

I also thank Gebin George from Packt, without whom this book release would have been canceled, without forgetting Ronn Kurien and Suzanne Coutinho.

Finally, I would like to thank Cyprien Pacme Nguefack, Stephane Capgras, and Gilberto Alberto, the mentors who inspire me in my daily life. I do not forget Sacker Ngoufack, my intern, Ramez Zagmo, for their services, and others who I could not name here.
