About

I turn data into decisions and products — from Power BI reporting at scale to autonomous AI agents and computer-vision models.

Currently CRM & Sales Data Scientist at ELPEN Pharma, where I automated 150+ monthly Power BI reports and built Python pipelines for data processing and analysis.

My background spans data analytics at IQVIA and Syscode, an MSc in Computer Science from the University of Piraeus, and an ongoing MSc in AI & Visual Computing (Univ. of West Attica & Univ. of Limoges).

I build in the open — an autonomous LangGraph data agent, and Querlytics, a full-stack AI SaaS that turns natural language into formulas.
