About Me

🧑‍💻 About me
I'm a software developer passionate about technology, specializing in programming and systems administration. Since I started in IT, I've enjoyed solving real-world problems with code, learning firsthand how a system works internally, and constantly advancing in areas like systems administration, scripting, and cybersecurity.

My curiosity about cybersecurity has led me to delve deeper into concepts of protection, process analysis, and technical automation, always with a practical and results-oriented approach. I am currently developing my own projects, which allow me to stay up-to-date with the rapid pace of technological advancements and provide higher quality instruction in my classes.

I have also competed in technical events: I won a silver medal at Andalucía Skills 2025 in the specialty of Network Systems Administration, which demonstrates my technical ability and commitment to practical excellence.

📚 My way of teaching
I like to teach in a clear, practical, and approachable way: nothing excites me more than seeing someone go from thinking "I don't even know where to start" to "I can do this myself." My classes are designed so that each concept has real-world applications from the very first minute, with exercises you can use in your own projects.

This is what I offer in my programming and technology classes:
Step-by-step explanations, without unnecessary jargon
Real code, not just theory
Exercises applied to practical situations
Close support and answers to your questions right away.
A pressure-free environment where you can learn at your own pace.

🚀 What skills should I bring to your classes?
✔ Connection between theory and real projects.
✔ Continuous and real learning.
✔ Ability to think like a computer scientist.
✔ Advanced knowledge and personal experience.

💡 My promise
I'm not just going to teach you "what something does."
I'm going to teach you how a developer thinks, how to structure code professionally, and how to solve real-world problems using programming.

If you really want to learn, from someone who has practiced and applied what they teach, I'm here to help you.

If you’ve ever felt that science and math are difficult, it’s probably because no one showed you how to think like a problem solver.
In my classes, you’ll learn not just formulas or code but how to truly understand concepts, apply them, and build strong logical intuition.

I teach:
• 🔢 Mathematics: From algebra and calculus to applied problem-solving for real-world use.
• 💻 Computer Science: Coding fundamentals (Python, C++), algorithms, and logical thinking for beginners and intermediate learners.
• ⚛️ Physics: Mechanics, thermodynamics, and practical examples that make abstract ideas simple and visual.

As a Software Engineer and Master’s student in Engineering at Nagoya University, I bring both academic knowledge and hands-on experience from real projects. My teaching approach is interactive, visual, and deeply focused on understanding over memorization.

Let’s turn complex problems into clear, step-by-step insights — and make learning something you genuinely enjoy.

Experienced and patient teacher of logic for computer science.

I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills.

Logic
The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof.
Topics include:
Propositional and Predicate Logic
Syntax and semantics
Natural deduction
Semantic tableaux
Correctness and soundness
Completeness

Formal languages and automata
A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language.

Topics include:
Regular languages, context-free languages
Finite automata, pushdown automata, Turing machines
Regular expressions
Regular grammar, context-sensitive grammar
Pumping lemmas for regular and context-free languages

Objective: To understand AI without fear, to use it to simplify one's life, to know how to identify digital traps, and to use Word, Excel, etc. without difficulty.

1: Demystifying AI (What exactly is it?)
AI is not a movie robot: Difference between fiction and reality.

How it works (simply): The image of the "giant library": AI has read billions of books and uses them to predict the continuation of a sentence or create an image.

Where is it already present? Spell checkers, Netflix/YouTube suggestions, GPS, and voice assistants (Siri/Alexa).

2: Using AI to make life easier
Conversing with AI (ChatGPT, Claude, Gemini):

Ask him to write an administrative email or a complex letter.

Summarize a long newspaper article or document.

Plan a travel itinerary or find recipe ideas with what's left in the fridge.

AI for creativity and memory:

Generate images to illustrate a birthday card (Midjourney, DALL-E).

Using AI to restore or colorize old family photos.

3: Learning to "talk" to AI (The Art of the Prompt)
The context method: Why "Give me a cake recipe" is less effective than "I am allergic to gluten and I am hosting 4 people, give me a simple chocolate cake recipe".

The expert's role: Learning to tell AI "Act like a travel guide" or "Act like an expert gardener".

4: Precautions and Critical Thinking (The Survival Guide)
"Hallucinations": Understand that AI can make false claims with complete certainty (never take medical or legal advice from AI without verification).

Privacy protection:

Never give sensitive data (social security number, passwords, bank details) to an AI.

Knowing that everything we write to the AI is potentially used to train it.

Spotting "Deepfakes":

How to recognize a doctored image or video (details on the hands, strange reflections, slightly metallic voice).

Verify the information: the golden rule of cross-referencing sources.

5: Ethics and Impacts (To go further)
Copyright: Who owns an image created by AI?

The environmental impact: The water and energy consumption of AI servers.

The future: Will AI replace us or assist us?
