Developed FOZUP, a comprehensive social sports platform featuring a microservices architecture. The app connects players, teams, and businesses using location-based discovery, social feeds, and event management. I engineered the full stack: a FlutterFlow frontend, a scalable backend with NestJS and TypeScript on Google Cloud, and Firebase/Cloud Functions for real-time features. The platform includes a robust gamification system with points and leaderboards, plus monetization via subscriptions and in-app purchases.
