Profile

About Me

I'm a Data Scientist and Data Engineer with dual Argentine–Italian citizenship, currently living in Italy. I hold a Master's degree in Data Science from the Università degli Studi di Salerno (UNISA), where my thesis explored cultural bias in artificial intelligence models from a Cross-Cultural Management lens.

My background spans over seven years in IT operations at UTN (Argentina), where I managed Active Directory, networks, and helpdesk systems — giving me a strong operational foundation that now complements my work in data pipelines, ETL/ELT, and business intelligence.

I enjoy building things: interactive dashboards, ML models, recommendation systems, and clean data workflows. I'm equally comfortable with exploratory analysis and production-ready reporting.
