About the Author

Santiago Fernández Muñoz: I started my career as a Linux and Windows instructor. At the same time, I also started to learn scripting programming languages such as bash and VBS that were useful for my work. During that period of my career, I realized scripting languages were helpful, but they were not enough to meet all my needs, so I started learning other languages like Java, PHP, and finally C#.I’ve been working as a Microsoft technologies consultant for the last 14 years, and over the last 6 years, I’ve consulted on Azure-related technologies. I’ve participated in different types of projects, serving in a variety of capacities from .NET developer to solution architect. Now I’m focused on developing custom industrial IoT solutions for my company and clients.
