About

I am an Elektroniker (electronics technician) in Germany, building on a practical background in electronics, electrical systems, troubleshooting, PLC technology and industrial automation.

I am now moving deeper into software and technology, with a focus on cybersecurity, data analytics and Python.

My approach is simple:

Understand the system. Build something. Break it. Find out why. Improve it.

That mindset comes from working with real technical systems, where guessing is usually a bad debugging strategy.

Learning philosophy

I am not trying to collect technology names.

I am building transferable technical understanding.

When I learn a tool, I want to understand:

What problem does it solve?
How does it work?
What can go wrong?
How do I test it?
How can I use it in a real project?

This is why my GitHub contains notes, experiments, assignments and projects alongside polished work.
