know me more
With the start of my Information Systems degree in 2018, I gradually became more focused on the IT field. Although I had always been interested in computers, the challenges and solutions presented by the course made me want to dive deeper into the area, especially because it is so broad. I began my career working as a computer instructor, which opened my eyes to how different people perceive technology in unique ways—whether it's how it's applied in social or professional environments, or how it functions at a basic level, from specific services to the most commonly used social networks. Through this experience, I realized that the field of Information Security is something that should be deeply explored, for both personal and logical reasons. That led me to pursue a postgraduate degree in Information Security, which has only strengthened my passion for technology and how it connects us all.
