About Me

Passionate about turning complex problems into elegant solutions

I specialize in building intelligent systems that bridge the gap between cutting-edge AI research and practical business applications. My mathematical background gives me a unique perspective on machine learning algorithms and their real-world implementations.

Currently working as a Freelance AI Engineer at EnergyAI Berlin, where I develop GenAI applications and robust data pipelines. I'm passionate about RAG systems, agentic AI, and the mathematical foundations that make neural networks so effective.
