I streamlined the design of a unified internal platform for Walgreens, consolidating fragmented HR and operational tasks into a single, cohesive app for 8,000+ employees. By implementing a modular, card-based UI, I delivered a personalized experience tailored to diverse roles—from pharmacy staff to corporate leadership—across both mobile and desktop. This strategic redesign eliminated system fragmentation and achieved a 20% increase in employee efficiency within the first three months of launch.
