Profile
Data analyst with an investigator’s eye. I turn messy operational and financial data into clear decisions through Excel, SQL, Python, and visualization.
I’m especially strong in financial modeling, reporting, reconciliation, and identifying the why behind a number—not just the number itself. I value accuracy, practical tools, and analysis people can actually use.
