IT Engineer @ University of Freiburg
Independent AI Research

I work on trustworthy local AI systems with a focus on Retrieval-Augmented Generation (RAG), fine-tuning small language models, and objective evaluation of LLMs. My work combines research, software engineering, and open-source development.

• Retrieval-Augmented Generation (RAG)
• Fine-Tuning Small Language Models (SLMs)
• Local AI Systems
• Information Retrieval
• LLM Evaluation
• XML Transformation with LLMs
• Open Source AI

• TSFT-RAG — Task-Specific Full Fine-Tuning for Retrieval-Augmented Generation
• Local RAG Systems for Research and Education
• LLM-based XML Transformation
• AI in Higher Education
• Fine-Tuning and Evaluation Pipelines

My fine-tuned language models are available on Hugging Face:
