Data Engineer at Bateleur building LLM-powered intelligence systems, including a market research RAG system analyzing internal documents.

At Bateleur, I develop data pipelines and intelligence systems for consulting, M&A, FinOps, and analytics. I maintain around 20 Apache Airflow DAGs and built a news classification and ranking pipeline that uses LLM APIs to produce customized sector newsletters.

I also published a RAG system for market intelligence and internal document analysis, using local VLMs to process charts and images from PDFs. Before Bateleur, I developed simulation and data-preparation pipelines for deep learning research at UFRGS, and analyzed high-volume experimental data at UFABC.
