Hi, I’m
Patryk.

Portrait of Patryk Kozak

I’m an AI Engineer, Data Scientist and AI & Data Consultant based in Vienna, Austria, with 5+ years of professional experience delivering technology and data solutions across the DACH market. My expertise spans machine learning, AI infrastructure, agentic AI, data platforms, MLOps, production-grade LLM applications and data products.

I combine strong technical depth with curiosity, clear communication and a practical approach to solving complex problems. I’m comfortable moving between hands-on engineering, open-ended research and collaboration with people from different professional and technical backgrounds.

This site presents my professional experience, technical expertise, current areas of interest and the projects that best demonstrate the value I can bring.

A little more about me

I like difficult questions, intellectual curiosity and work with a purpose.

I’m interested in solving complex problems and turning ideas into practical results. My work combines technical depth, analytical thinking and clear communication, allowing me to move comfortably between engineering, data and business needs. I value careful experimentation, reliable evidence and solutions that are useful, understandable and built with a clear purpose.

Engineer

I enjoy seeing how the whole technical picture fits together—from Python, machine-learning and generative AI models to AI agents, APIs, infrastructure, deployment and observability. I’m especially drawn to building systems that are technically strong, reliable and genuinely useful in practice.
