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