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 — updated via APNs, event-driven backend, and Stripe-triggered workflows. This is not a UI demo — 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 → insurance activation Backend APIs → policy generation Apple Wallet (.pkpass) → digital identity APNs → real-time updates Live Activities → session-based tracking Event scheduler → state transitions Key Features (Make this VERY structured) 📱 Apple Wallet Integration Dynamic .pkpass generation Secure signing + pass lifecycle management Wallet-based identity layer 🔔 Real-Time Updates (APNs) Push-triggered pass refresh system No direct data push — Apple pull-based update model ⏱️ Live Activities System Session-based lifecycle tracking State transitions: Scheduled → Active → In Progress → Completed Mid-session override support 💳 Payment & Activation Flow Stripe webhook → backend orchestration Auto-activation of insurance coverage ⚙️ Backend Architecture Event-driven system design Serverless APIs (Vercel) Background scheduling (Inngest/Cron) #AppleWallet #PassKit #iOSDevelopment #LiveActivities #APNs #AppleDeveloper #iOSArchitecture #MobileBackend

Cover image for This project focuses on turning
This project focuses on turning raw Meta Ads data into clear, decision-ready insights for performance optimization and budget allocation. Instead of reporting isolated metrics like CPC or CTR, the goal was to understand where spend actually converts into quality leads — and where performance silently breaks down across the funnel. The dashboard was built to support daily and weekly decision-making for marketing and growth teams.

Cover image for I built a marketing performance
I built a marketing performance analytics dashboard that helps marketing teams quickly identify which campaigns, audiences, and ad groups are actually driving conversions — and which ones are wasting budget. The goal of this dashboard is simple: “Inside a campaign, what is actually working?” Instead of only tracking high-level metrics, the dashboard breaks performance down into campaign and ad group level insights, enabling faster optimization decision The dashboard tracks the full marketing funnel: Impressions Clicks Conversions Spend CTR (Click Through Rate) CVR (Conversion Rate)
