Production-Ready SaaS Backend with Advanced Analytics & Redis Optimization

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

Buffered analytics processing for high-traffic environments

IP-based geo tracking (country & governorate level)

Full time-based analytics (hour, day, frequency)

Clean, scalable RESTful APIs

Multi-level RBAC system

?️ NFC & Cards:

Each card acts as a dynamic digital profile

NFC tag claiming and lifecycle management

Card reassignment between employees without data loss

Full scan & lead tracking

? Company Features:

Professional company profiles with custom slugs

Employee & department management

Centralized company analytics

Full visibility over all employee leads

? Super Admin:

Full system control

Manage users, companies, orders, products, and NFC inventory

Global analytics and monitoring

? This system is built for real production usage, not a demo or prototype.
