Tech Support for Legacy Systems and Troubleshooting Experts

Àpd 46 € /h

Is your printer refusing to work with your computer again? Are you stuck with a weird error that no one on the forums seems to understand? Or maybe you have an ancient device that stores priceless data, but no modern system will talk to it? That’s where I come in - call me your digital detective.

I specialize in solving the kinds of tech problems most people walk away from—legacy hardware, software compatibility issues, obscure drivers, and cryptic error messages. Whether it’s a memory leak in a 20-year-old Palm PDA or making two completely unrelated systems communicate, I’ve been there and I've fixed that.

If your setup is unique, outdated, or just plain broken, I’ll treat it like a puzzle worth solving. Tech archeology meets modern ingenuity. I’m also happy to travel and work on-site if needed—sometimes the only way to truly understand a system is to sit down with it in person.
“Legacy systems fear him. Devs envy him. Managers don’t understand him.” - one of my clients, probably.

Présentation

Having two little sisters provided me plentiful opportunities to experience first-hand what it's like to teach youngsters. With my guidance they became fluent in English as well as the language of music and theory. I never forced them to do as I say, nor did I penalize them for failing to prepare - just showing up is always sufficient. There is nothing in the world more fulfilling and meaningful than to see week by week the little steps a student takes on the path of learning. To see the milestones, the techniques they weren't able to perform just a few days prior, to see a delightful gleaming smile of success, the fact that they believed in themselves. This is what motivates me more than anything else in my piano and programming teaching voyage.

Studying and practicing can be stressful sometimes. It can be quite difficult in the early phases to train those rebellious fingers actively trying to sabotage a seemingly easy piece of music or program. It takes endurance to sit down on the same every day to practice, often without much improvement. But over time, it always becomes crystal clear, that every single second of practice counts, that practice itself improves self-control, not only within the confines of music and computers but also in everyday life.

He who never fails never tried to succeed either. The prerequisite of mastery is being a beginner.

Whether you're a curious beginner or someone already dabbling with machine learning, I offer hands-on guidance through the AI jungle. Using libraries like Pandas, Scikit-learn, TensorFlow, and OpenCV, I’ve built projects ranging from eye-tracking systems to classification models. I know how to explain complex concepts in simple terms—and help you build real, working prototypes.

From your first regression model to deploying your neural network, I’ll be your guide. Whether you want to understand the math behind it or just want results, we’ll move at your pace. available remotely across Europe.

While adults are still debating whether kids should use AI, they are already using it.
The question isn't "should they?" it's "how do we do it intelligently?"

In this course, your child will discover:
✓ What AI actually is: not magic, not mystery. How machines think, what they can do, what they can't
✓ How ChatGPT really works: not just "ask a question and get an answer," but why it responds that way, where it fails, when to trust it
✓ What LLMs are (Large Language Models): in language they understand, not tech jargon
✓ Create with AI: custom avatars, interactive stories, real projects using real tools
✓ Think critically about AI: Bias, privacy, creativity. What does AI do better than humans? What can't it do?
✓ Real-world applications: How AI transforms medicine, education, art, gaming, everyday life

Why this is different:
Most AI courses for kids teach "here's the tool, use it." I teach how to think about AI.
Your child will learn to see AI not as black magic or a solution to everything, but as a powerful tool with real limits.
And, more importantly: that they can control how they use it.

What they take home:
Real projects they created (custom avatar, interactive app, analysis of a real AI case study). A genuine understanding of how it works. And the ability to use AI responsibly and creatively.

Format: Online | 60–90 min sessions | Flexible, adapted to their age and pace

For curious kids asking "How does ChatGPT actually know things?"

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?
