AI Engineer at Self Employed

I moved from the arts into tech — and remained an artist.Today, I work at the intersection of language and structure, combining analytical thinking with large language models to make information accessible, comparable and explainable. I focus on building RAG-based systems and knowledge-driven prototypes that help navigate complex domains such as politics and public administration. Technically, my background includes: 🔹 RAG & LLM-based systems (retrieval, chunking, evaluation, prompt logic) 🔹 Data analysis & structuring (Python, SQL, exploratory analysis) 🔹 Foundations in machine learning, statistics and forecasting from academic and project-based work I’m interested in collaborations, pilot projects or teams that value thoughtful system design, ethical AI and real-world impact over hype.I moved from the arts into tech — and remained an artist.Today, I work at the intersection of language and structure, combining analytical thinking with large language models to make informatio
