Spotlight Solution

AI-Powered Fraud Detection System

The Challenge: A leading payment processor was facing rising transaction fraud and a high rate of false positives, leading to lost revenue and frustrated customers.

The Solution: We built a real-time anomaly detection engine using machine learning that analyzes transaction patterns instantly. The system reduced fraud by 35% while cutting false positives by half.

1

Real-Time Ingestion

High-throughput Kafka pipelines ingest thousands of transactions per second from multiple payment gateways.

2

ML Inference Engine

Ensemble models (Random Forest + Neural Networks) score each transaction for risk in under 100ms.

3

Automated Response

High-risk transactions are automatically blocked or flagged for manual review via a custom admin dashboard.
