COVID-19 Response: Rite Aid Vaccination System

Rapid deployment of end-to-end vaccination scheduling at national scale

The Challenge

During the COVID-19 pandemic, Rite Aid needed to rapidly deploy a comprehensive vaccination scheduling system to serve millions of customers nationwide. The stakes were high - public health depended on efficient vaccine distribution.

  • Urgent timeline with public health implications
  • Need for end-to-end solution: scheduling, inventory management, and reporting
  • National scale deployment across thousands of pharmacy locations
  • Integration with existing Rite Aid mobile apps (iOS and Android)
  • Coordination with backend teams, pharmacy operations, and external health authorities
  • High reliability requirements - system failures could impact vaccine access

The Solution

Led mobile engineering effort to design and implement a comprehensive vaccination scheduling system integrated into existing Rite Aid pharmacy apps, coordinating across iOS, Android, and backend teams.

Approach

  1. 1Collaborated with product and backend teams to design end-to-end user flow
  2. 2Architected mobile integration for both iOS (Swift) and Android (Kotlin) apps
  3. 3Built real-time appointment availability checking with inventory synchronization
  4. 4Implemented vaccination record management and appointment confirmation
  5. 5Coordinated with pharmacy operations to ensure smooth in-store experience
  6. 6Established monitoring and analytics to track system performance and usage
  7. 7Rapid iteration based on user feedback and operational requirements
