Case study: I built a food delivery app that hit 100M+ users and processed $2B+ in transactions.
The challenge: real-time order tracking across thousands of concurrent deliveries without lag.
The solution: React Native frontend, Node.js + PostgreSQL backend, Redis for caching live location data, AWS for auto-scaling infrastructure.
Key features I built: live GPS tracking, smart route optimization, multi-vendor marketplace, payment processing, push notifications, admin dashboard.
