Real-Time Fraud Detection Microservice Suite
System Overview
An event-driven microservice ecosystem designed to detect fraudulent transactions in real-time using high-throughput streaming and intelligent rule evaluation.
Engineering Governance
Core Developer defining the event-driven strategy for real-time risk assessment and automated flagging.
Full-Stack Architecture
Leverages Apache Kafka for streaming transaction data through a Python-based rule engine. Utilizes Redis for sub-millisecond evaluation of velocity rules to flag suspicious activity instantly.
Business Impact
Real-time detection pipeline with sub-second response times.
Scalable microservices architecture capable of handling thousands of events per second.
Automated flagging of complex fraudulent patterns using velocity and pattern analysis.
Real-time processing of high-volume transaction streams without introducing significant latency.
Implemented asynchronous processing with Kafka and sub-millisecond rule lookups using optimized Redis data structures.
