Cover image for Do you wanna build a
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

I
PDFConverterOnlineFree – Node.js PDF Tool I built this project as a practical, real-world PDF tool that runs completely online and doesn’t rely on any database. The idea was simple β€” most PDF tools out there are either paid, slow, or store user files. I wanted to create something lightweight, fast, and privacy-friendly using open-source tools. πŸ”— Project Link: https://github.com/deepakpatilauthor/PDF-Tool-Node-JS-Project What this project does This web app lets users: Convert PDFs to formats like Word, Excel, and images Convert files back into PDF Merge, split, and compress PDFs Use everything without signing up All files are processed temporarily and deleted automatically, so nothing is stored. How I built it I used Node.js for the backend and connected it with: Ghostscript for handling PDF operations like compression LibreOffice for document conversions The whole system is stateless (no database), which keeps it simple and fast. Why I built it this way I wanted to prove that you don’t always need paid APIs or heavy infrastructure to build something useful. With the right open-source tools, you can create a solid, production-ready app. What I learned Working with system-level tools like Ghostscript and LibreOffice Handling file uploads and processing efficiently in Node.js Building a clean workflow without relying on a database Thinking about performance and user privacy Final thoughts This project is a good example of how I approach building tools β€” keep it simple, make it useful, and avoid unnecessary complexity.
