At Unipartner, I developed a Vanna.ai Text-to-SQL chatbot for answering natural-language questions over enterprise data. I also built data pipelines and a Streamlit interface to display query results as text and interactive charts.

In my independent projects, I built a branching AI chat application with FastAPI, PostgreSQL, and LangGraph, and a Telegram assistant that transcribed and summarized media into structured notes. For my MSc research, I adapted SAM2-UNet for satellite-image semantic segmentation; my first-author paper was accepted and presented at EPIA2026.
