Project Overview
This massive-scale telecommunications platform serves as the backbone for mobile rewards and subscription services across South Africa's major network operators. Built with microservices architecture and Node.js, the system processes millions of transactions daily while maintaining 100% uplink reliability to carrier networks.
Microservices Architecture
The platform features sophisticated subscription management workflows, real-time balance tracking, and intelligent rewards distribution algorithms. Advanced gRPC communication ensures high-performance inter-service communication, while PostgreSQL and Big Data solutions provide robust data storage and analytics capabilities.
Carrier Integration
100% uplink reliability to major network operators (MTN, Vodacom, CellC & Telkom) demonstrates the platform's enterprise-grade connectivity and redundancy systems. The architecture supports millions of daily transactions without data loss or service interruption.
Monitoring & Performance
Comprehensive monitoring through Sentry.io provides real-time system health visibility and proactive issue resolution. The system's modular architecture enables rapid deployment of new features and seamless scaling to accommodate growing transaction volumes across multiple network operators.
