About

I am an independent IT consultant and software developer based in Mannheim, Germany, with around 18 years of practical IT experience including vocational training. My core work covers Python, SQL, Excel/VBA, Access, Power BI, ETL, data quality and automation for established business systems.

I build internal tools, reporting pipelines and local AI/RAG workflows using Ollama, PyTorch and Qdrant. I also have practical experience evaluating AI responses and annotating text, image and audio data through Outlier and Clickworker. I deliver clear technical documentation and training, and previously founded and led a martial arts school with up to 10 instructors. German is my native language and I speak English fluently.
