Live Activities for Real-Time User Engagement

Implemented iOS Live Activities for the Best Buy mobile app, delivering real-time updates to users' lock screens during high-traffic events like product launches and sales.

Built resilient architecture with exponential backoff and circuit breaker patterns to maintain reliability at scale. This system enabled customers to track order status, inventory alerts, and flash sale countdowns directly from their lock screen without opening the app.

The implementation required deep integration with Apple's ActivityKit framework and coordination with backend services to push updates efficiently during peak traffic periods like Black Friday and product launches.
