Walmart Exchange was Walmart's proprietary digital ad platform — built to let suppliers leverage first-party purchase data across 5,000+ US stores to target and optimize advertising on social platforms. My role sat at the intersection of media, product, and creative: ensuring suppliers' campaigns were placed in the right features and formats, maintaining creative quality standards across all social placements, and working directly with Facebook and Pinterest product teams on new feature development with Walmart's specific needs in mind — including mobile app integrations and advertising data partnerships that allowed insights to flow back into Walmart's targeting and measurement infrastructure.
