My experience includes collaborating with cross-functional teams such as Policy, Legal, and Engineering to improve workflows, strengthen enforcement systems, and support platform integrity. I am highly detail-oriented, analytical, and committed to protecting users while ensuring fair and consistent application of policies. My technical skills include SQL, Excel, Zendesk, and performance analytics.
