Audit-grade rigour, applied to data.

Data analyst with a background in public-sector audit and finance, building analytics solutions with Python, SQL, Power BI and Tableau. I bring audit-grade rigour in data validation and controls to hands-on delivery, structured around CRISP-DM.

The projects here show the tools and skills behind that work. Each one links to its code, dashboard or demo.
