About

I’m Marek — principal engineer, AI researcher, and product builder.

I like working at the intersection of research, systems, and real-world applications — especially when the path isn’t clear yet. Something bothers me, I go deep enough to understand the problem, hack toward a solution, and care whether the result is actually useful. Then I write down what I learned.

Research when needed. Build when possible. Ship what matters.

Background

I started my journey into computer science at 15, coding in C++ without internet access, in good old fashioned Bloodshed C++. Nearly 20 years later, I have a Master’s degree in Computer Science and Statistics from the University of Economics in Bratislava. I’ve done machine learning and built distributed systems for early to mid-stage startups. Right now I’m a Senior AI and Machine Learning Researcher at ESET, combining cutting-edge AI with cybersecurity.

Professional interests

• Machine learning
• High-performance and distributed computing
• Reverse engineering and vulnerability exploitation
• Secure coding

Otherwise

Father of three sons, cat person, and a book worm committed to lifelong geek-hood. The same drive applies off the keyboard: I’d rather build than consume, act than ruminate, and learn something hard because it’s there.
