About Me
I began my professional journey by founding the first Blockchain organization in Asturias, actively promoting this disruptive technology for over 5 years. This early involvement shaped my perspective and technical expertise, now applied in my roles as Head of Cybersecurity and Systems Supervisor.
My passion for cybersecurity began early in life. Now, I apply that passion in my day-to-day work, leading critical efforts to secure my company’s systems and ensuring our resilience in an increasingly complex digital world.
My journey in technology began with network engineering, where I earned my CCNA certification. Today, this foundation allows me to lead IT operations with confidence and design secure, scalable solutions for complex environments.
