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.

Is AI just for adults? Absolutely not!

This is the perfect course for children (and their parents) to truly understand what Artificial Intelligence is, how it works in our daily lives (from Netflix to video games), and, most importantly, how to use it safely and creatively.

Led by a teacher with over 10 years of experience in technology and coaching, your child will learn to:

Identify what is and what is not AI (the myth vs. the reality).

Play the game of 'training' an AI with simple and fun examples (basic Machine Learning).

Ask their first intelligent questions to generative AI tools to create digital stories or art (introduction to Prompt Engineering).

Understand the importance of ethics and safety when using these new technologies.

This course will transform your child's curiosity into a fundamental skill for the future. We use a personalized coaching approach to ensure complex concepts are accessible and exciting, especially for students with Special Educational Needs (SEN)!

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

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?

I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics.

I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since.
I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors.
I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...)

I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge.
I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence.

I can travel to the student's home or also conduct the lesson via Zoom/Google Meet.

Many students today use AI tools like ChatGPT, but often in an unsafe or improvised way. Legitimate questions arise: Is it allowed? How can mistakes be avoided? How can AI be used without losing control of one's own thinking?

This course isn't about shortcuts or "machine-done work." It focuses on understanding AI as a tool and learning to use it consciously and responsibly. We work with concrete examples from the university setting and show how AI can support learning without compromising academic integrity.

One of the course's central themes is AI as a research tool. We'll explore how to define topics, formulate effective research questions, and structure a project from the outset. AI can help gain an overview and organize ideas, but we'll also clearly analyze its limitations and the need for critical self-reflection.

From there, we move on to academic writing. From developing outlines and arguments to improving style and clarity, AI can be a valuable tool. We demonstrate how to work with drafts, detect inconsistencies, and avoid common errors that often cause problems in academia.

Another section is dedicated to learning with AI. Explaining complex texts, clarifying concepts, reviewing content, and checking one's own understanding are especially valuable uses if the right questions are asked. The goal is to use AI actively, not passively.

Finally, we use AI as an intellectual sparring partner. Not as a substitute for our own thinking, but as an interlocutor that helps to compare arguments, raise objections, and explore other perspectives. This is where AI's greatest real value often lies: thinking better, not thinking less.

The course is designed for students of any discipline. No prior knowledge is required. The goal is to gain confidence in using AI and learn how to integrate it productively and responsibly into university studies.
