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 Pacôme 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.
