Lead creative experimentation in partnership with designers and content creators, driving continuous learning through structured A/B testing. Leverage Tableau and other BI tools to build reporting, uncover insights, and support strategic decision-making. Partner closely with Data, Product, Creative, and Marketing teams to ensure accurate measurement, attribution, and experiment design.
