I designed and implemented a production-ready SaaS backend for a real-world platform based on digital business cards and NFC technology, with advanced analytics and high-performance optimization.
The system supports multiple personas (Individuals, Companies, Employees, Super Admin) with full role-based access control and scalable architecture.
⚙️ Technical Highlights:
Redis caching layer to reduce database load

Full time-based analytics (hour, day, frequency)
Clean, scalable RESTful APIs
Multi-level RBAC system
