Data analyst working across SQL, Python, Power BI, and Excel. My projects cover product analytics, cybersecurity risk analysis, consumer behavior, and education insights. Each one is built end to end, data modeling, analysis, statistical validation where relevant, and a dashboard or report designed for a business audience.

This page is a working portfolio. Everything here links to the actual project on GitHub.
