I specialize in administering and teaching Windows Server 2022 Administration Fundamentals to small, medium, and large enterprises. My goal is to keep trainees constantly challenged to learn how to set up and manage servers efficiently without overwhelming them. I cover topics such as Active Directory management, DNS and DHCP configuration, and Virtual Machine setup. After each lesson, I provide hands-on assignments to ensure full understanding and provide periodic reports to track trainees’ progress.

This class is for aspiring IT administrators who want to learn how to set up and manage Windows Server 2022 effectively. The focus is on learning how to set up servers, optimize their performance, and provision virtual infrastructure for enterprises. If you are a beginner, don’t worry, all concepts are explained clearly from the beginning to ensure complete understanding.
It is preferable for each student to have a laptop with the ability to run programs such as VmWare.

If you're thinking it's time to move away from paid commercial services, often American (thanks to Messrs. Trump, Musk, Zuckerberg, etc.) and turn to free solutions over which you take control, Linux may be an alternative for you.
Together, we can walk through the process: assess your current situation and needs, determine if Linux is a possibility, and then develop a learning and migration plan that I can support you in, based on your wishes.

As a university professor of computer science and a Linux fan for over 30 years, I can help you familiarize yourself with this system, or even adopt it as a replacement for commercial products.

This course introduces students to the essential role of data annotation in artificial intelligence and machine learning. Learners will gain a clear understanding of how raw data is transformed into structured, labeled datasets that enable AI systems to learn, interpret, and make accurate predictions.

Through guided instruction and practical examples, the class explores different types of annotation, including text, image, audio, and video labeling. Students will learn industry-relevant techniques, annotation standards, and quality control practices that ensure consistency and reliability in real-world AI projects.

The course emphasizes hands-on learning, allowing participants to practice annotation tasks and understand how their work directly impacts the performance of AI models. By the end of the class, students will have the foundational knowledge and practical skills needed to begin working on data annotation tasks or pursue opportunities in the AI and data industry.

Stuck with SMR, ASIR, networking, systems, or cybersecurity?
You don't need a miracle: you need it explained to you properly.

My name is Rubén Martos. In 2025 I realized something: many students failed not because they were bad, but because nobody explained things to them properly.

I thought, "If I could understand it, I can teach it. And I can do it better."

I am an SMR technician with a distinction for Best Academic Record, Erasmus+ experience, and I am currently in my final year of ASIR (Administrative Systems and Network Administration). I have worked in support, systems, and cybersecurity for companies in Spain and Portugal, and I manage an ethical hacking blog.

Since then, at Avanza de Verdad we have had a clear mission:
that you understand computer science clearly, practically, and with results.

📌 Classes we offer
• SMR, ASIR and IT from scratch
• Networks, Cisco Packet Tracer
• Linux, Windows Server, scripting
• Databases and cybersecurity

🧠 Our method
• Get to the point
• Learning by doing
• Apply what you have learned

🎯 What are you taking with you?
• Clear and direct explanations
• Preparation for resits and exams
• Help with internships, assignments, and projects
• Answering questions even outside of class
• To truly move forward, not just to pass

We're going to make real progress 🚀
