Walmart Wireless Activation Platform

Opportunity

In 2022, Walmart faced an urgent business challenge when their legacy Wireless Associate Retail Platform (WARP) couldn't support T-Mobile integration following the Sprint-T-Mobile merger—a $50M revenue opportunity at stake. The outdated system created significant friction for both sales associates and customers, with transactions taking 30+ minutes, frequent system crashes, and unintuitive interface.

Solution

I created a scalable platform architecture that could support multiple carriers (T-Mobile initially, with Verizon and AT&T planned) through a consistent user experience. This required implementing a dynamic carrier-driven catalog system and creating flexible workflows that could accommodate carrier-specific requirements while maintaining a unified interface.

Results

The redesigned platform successfully launched in Walmart stores (2,132 locations), significantly reducing transaction times by -33% and improving both associate efficiency and customer satisfaction. The solution became the first production application using Walmart's "Living Design: Mega" design system and provided a scalable foundation that could efficiently onboard additional carriers without redesigning the core experience. Most importantly, the project demonstrated how targeted UX decisions could solve business-critical problems while creating a sustainable platform for future growth, even within extreme technical and resource constraints.
