Chi sono
I'm a data analyst with 5+ years of hands-on experience turning messy data into clear, decision-ready answers. I work daily with SQL and Google BigQuery, Power BI/DAX, and Python, and I've built everything from complex analytical queries and cohort/retention reports to automated dashboards and data scrapers. My background is in a high-volume, metrics-heavy industry, so I'm comfortable with large datasets, tricky joins, window functions, and performance optimization. I care about accuracy, clean logic, and delivering results you can actually act on.
