Tech Support for Legacy Systems and Troubleshooting Experts

A partir de 54.48 $ /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If your setup is unique, outdated, or just plain broken, I’ll treat it like a puzzle worth solving.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.

Acerca de mí

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.

AI & Machine Learning Mentor / Developer for Students & Professionals

48.56 $ /h

“AI is the future.” You’ve heard it before, but what does it actually mean? Facial recognition, recommendation systems, self-driving cars—it all starts with data, algorithms, and code. The best part? You can learn it too.

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.

Custom Python Automation Scripts for Everyday Efficiency

68.69 $ /h

Tired of doing the same tedious task over and over again? What if a small Python script could save you hours—every week? Whether it’s organizing files, renaming batches of documents, equalizing the volume of your MP3s, or auto-filling forms, automation is the silent superpower of the tech-savvy.

I build personalized scripts that do exactly what you need, no more, no less. These are not generic tools, but lightweight, purpose-built solutions designed to run on your system and make your workflow smoother.

If you’ve ever said, “There must be a better way to do this,” there probably is. Let me build it for you. Smart code for smart people.

Most kids think coding is for "smart kids" or "future programmers."
It's not. Coding is how real people solve real problems.
In this class, we skip the theory. Your child creates real things.

What they'll do:
✓ Build real projects in Scratch: a working game, an interactive animation, a story they coded
✓ Program virtual robots: solve real-world challenges (navigate a maze, automate a task, build a system)
✓ Create in Minecraft Education: design worlds, automate constructions, solve logic problems
✓ Experiment with different languages: not just learn "the right way," but understand that there are many ways to think about a problem
✓ Collaborate and share: work with other kids, get feedback, improve their work
✓ Develop logical thinking: not just for coding, but for anything: solving math problems, science challenges, real-world situations

Why this is different:
We don't teach syntax. We teach how programmers think.
Most children's coding courses say "here's the code, copy it." We teach "what problem are we trying to solve? How could we break it into steps? What options do we have?"
When your child learns to think like a programmer, they can learn any language afterward.

What they take home:
A portfolio of 3–4 completed, working projects. The ability to say "I built this." And the deep understanding that code is a tool to make real things happen.

Format: Online or Barcelona | 60–90 min sessions | Flexible pace, no prior experience needed
For curious 8-12 year olds who want to build.

Python is one of the best, if not the best, language to start learning programming. It is also one of the most widely used languages today, especially in cutting-edge areas such as machine learning.

This popularity means that Python is constantly evolving. It offers a wide range of tools and libraries, which are free and very varied.

As an aeronautical engineer, I like to share my knowledge and derive satisfaction from it by teaching and motivating others.

I'm used to working with people of different ages. I believe in the importance of segmenting learning, visualizing progress, setting concrete goals and practicing regularly.

Beyond these general principles, there is no magic rule or method. Some approaches work with some students but not with others. Adaptation to individual needs is therefore the main objective of private lessons. So I will do my best to find what motivates and helps my student.

I am patient and let students find the solutions themselves. If students are motivated, they can ask me questions outside of private lessons to learn more quickly by taking the initiative.

During the first lesson, I ask them what they need to do, then I give them exercises for the other lessons.

I have a C1 level in English (TOEIC). I have many digital and print resources to help students, such as past exam papers, exercises, quizzes in English, and good YouTube channels. I can also advise students on their study methods.

The courses are designed for students up to the third year of university (BAC+3) in mathematics, computer science, or English, and up to the second year of university (BAC+2) in physics, chemistry, and biology. I can also help students prepare for the TOEIC exam, offering helpful tips and strategies. If you need Spanish lessons, I can provide techniques to help you learn much more quickly.

The classes are held via video conference.
