About
I’m Polychronis Pattakos, an Electrical & Computer Engineer (PhD) and full-stack AI engineer based in Athens. I build and deploy LLM-powered applications end-to-end—especially agentic tool-calling systems and citation-grounded RAG pipelines—combining rigorous applied ML with practical production engineering across APIs, dashboards, and CI/CD.
Beyond LLM applications, I apply deep technical reasoning to sensor systems and data analytics, including time-series anomaly detection, sensor fusion with Kalman filtering, and explainable risk-scoring models grounded in real-world methodologies. I also enjoy translating complex research into working products, coordinating technically complex projects, and teaching AI and computer science fundamentals at the university level.
