Hello World

I am a Researcher and Engineer currently at the Institute for Automation and Applied Informatics (IAI) at KIT. My work sits at the intersection of AI-driven cybersecurity and critical infrastructure. I am currently focused on the capabilities of Large Language Models (LLMs) in offensive and defensive scenarios for smart grids.


With a background in engineering and fullstack development experience, I combine systems engineering with modern software practices to build intelligent, resilient solutions.
