Tech Support for Legacy Systems and Troubleshooting Experts
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If your setup is unique, outdated, or just plain broken, I’ll treat it like a puzzle worth solving.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.

About Me
Translated by Google. Click to view original.
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.

Jerry is good at walking you through concepts and explaining how python really works.
Expert programmer, deep knowledge of Python. Recommended!
Reliable, caring, knowledgable, and fun to work with! Totally recommend! Thank you once again, Gergely! :)
As someone struggling with learning programming in Python for so long, Jerry's lessons literally saved me. His clear explanations helped me understand the concepts better, and the examples he provided helped me concretize the topics in my mind so that I was able to apply them by myself later. He was very patient and helpful when explaining the topics and when giving me time to think about the possible formulations of the algorithms, which released the stress of passing my university course and enabled me to actually understand the essence of Python and how to think when programming.
It's not every day that you come across a mentor who changes your perspective and approach to learning, especially in the world of programming. However, I have been fortunate enough! He always takes the time to address my queries, making sure that I fully understood each topic before moving on. He also often goes the extra mile, be it through providing extra resources, setting up additional practice sessions, or just being available for guidance and encouragement.Thank you :)

What is this AI thing everybody is talking about these days? Do you want to understand technology at a deeper level? Are you interested in how common applications fundamentally operate? Would you like to improve your logical and analytical skills (not to mention endurance and patience)?
Learning to code - a phrase that is all too popular nowadays. Still, dealing with programming languages is kind of inevitable in every sector. And by becoming fluent in Python or AI techniques you broaden the spectrum of your possibilities, in academia, in the job market and in your personal life too!
There is simply no better language than Python to begin with on your exciting coding journey. And there is also no better way of doing that than by having someone personal to ask questions to. This way you not only don't have to waste time and effort on a stupid typo, but you're also less likely to give up. Effort * Encouragement = Success!
“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.
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.
You found an old file—something important, maybe even sentimental—but your computer just won’t open it. Or maybe you’re dealing with a custom software system that uses a weird, proprietary format. What now?
I specialize in rescuing, translating, and reverse-engineering data formats that most people don’t even recognize. Whether it’s a corrupted calendar file from a PDA or a bizarre export from a dead program, I approach it like a digital archaeologist.
It’s not magic—it’s patience, logic, and deep technical skill. If something should work but doesn’t, let me figure out why.

Learn to program and code with Scratch while having fun* This digital training aims to introduce you to the Scratch tool and through the game world, and gradually, to discover programming concepts such as loops, conditions or variables. It is aimed at anyone who is new to Scratch and who wants to create games and animations.
* Learning programming will allow students to develop their skills and will certainly allow them to meet the expectations of the future working world and emerging careers.
* In addition, learning programming allows the development of algebraic, algorithmic and computational thinking. Programming also helps to improve and develop students' sequencing ability, as well as their communication skills. Thus, there are several advantages to teaching programming, but the important thing is to remember that this learning teaches students that digital is not only for entertainment, but that it is possible to become creators. active and creative content.
