Fraud Payment Detector

A real-time payment fraud detection system built with Go, Kafka, and Redis. Detects anomalous transactions using simple, configurable rules.

Core Rules

• High-Frequency Transactions – flags rapid successive transactions.

• Large Amounts – flags transactions exceeding thresholds.

• Geographical/Velocity Checks – flags impossible travel patterns between transactions.

cd fraud_payment_detector
