Transactional Dashboard
A high-throughput transactional operations dashboard providing real-time monitoring, anomaly detection, and drill-down reporting across distributed payment flows.
The Challenge
Operations teams needed a single pane of glass to monitor thousands of daily transactions, detect anomalies instantly, and audit trails across multiple payment providers.
The Solution
Built with React and WebSockets for live transaction feeds, NestJS aggregation service pulling from multiple payment APIs, Redis for caching, and PostgreSQL for historical reporting. Implemented threshold-based alerting and CSV/PDF export.
