About me

In 2025, I realized something: many students were failing not because they were bad, but because no one was explaining things properly. And I thought: “If I was able to understand it, I can teach it. And I can do it better.” I’m a technician in SMR with a mention for Best Academic Record, and I’m currently studying ASIR. I’ve worked in support, systems, and cybersecurity in companies in Spain and Portugal, and I run an ethical hacking blog. Since then, my mission has been clear: helping people understand IT with clarity, practice, and real results. That’s the spirit of Avanza de Verdad. My method: • Go straight to the point: No confusion, no textbooks thrown at you. I explain exactly what you need to learn. • Learn by doing: You don’t copy commands—you understand them. I focus on making sure you know what you’re doing and why. • Results you can feel: From the very first class, you apply what you learn. No useless theory, just real skills. If you’re looking for a teacher who explains things properly and helps you truly move forward, I’ll be happy to help you.
