Do you wanna build a similar to a production-style Apple Wallet system that turns health insurance into a real-time, Live Activity-powered digital experience β€” updated via APNs, event-driven backend, and Stripe-triggered workflows. This is not a UI demo β€” it’s a full backend system design for real-world wallet-based experiences. Traditional health insurance systems are static, fragmented, and disconnected from real-time user experience. Users don’t know: Coverage status in real-time Claim updates instantly Appointment lifecycle status This project solves that using Apple Wallet + Live Activities + event-driven architecture. I designed and built a system that connects: Stripe payments β†’ insurance activation Backend APIs β†’ policy generation Apple Wallet (.pkpass) β†’ digital identity APNs β†’ real-time updates Live Activities β†’ session-based tracking Event scheduler β†’ state transitions Key Features (Make this VERY structured) πŸ“± Apple Wallet Integration Dynamic .pkpass generation Secure signing + pass lifecycle management Wallet-based identity layer πŸ”” Real-Time Updates (APNs) Push-triggered pass refresh system No direct data push β€” Apple pull-based update model ⏱️ Live Activities System Session-based lifecycle tracking State transitions: Scheduled β†’ Active β†’ In Progress β†’ Completed Mid-session override support πŸ’³ Payment & Activation Flow Stripe webhook β†’ backend orchestration Auto-activation of insurance coverage βš™οΈ Backend Architecture Event-driven system design Serverless APIs (Vercel) Background scheduling (Inngest/Cron) #AppleWallet #PassKit #iOSDevelopment #LiveActivities #APNs #AppleDeveloper #iOSArchitecture #MobileBackend
