Abstract: 
The exponential growth in digital payment volumes has exposed critical limitations in traditional payment processing architectures, particularly in handling real-time fraud detection and maintaining sub-second transaction latencies at scale. This paper presents an innovative hybrid architecture combining AI-driven fraud prevention with Java Spring Boot microservices for high-throughput payment orchestration. Our proposed system integrates Apache Kafka for event streaming, Redis for caching, and a novel ensemble learning model that combines gradient boosting with deep neural networks for real-time fraud detection. The methodology employs feature engineering techniques that extract both transactional patterns and behavioral biometrics, achieving a 99.7% fraud detection accuracy while maintaining average transaction processing times of 47ms. Experimental evaluation using a dataset of 2.3 million transactions demonstrates a 340% improvement in throughput compared to traditional monolithic systems, with a 67% reduction in false positive rates. The system successfully processes 50,000 transactions per second while maintaining ACID compliance and PCI-DSS security standards. This research addresses the critical gap between payment system scalability and real-time security requirements, providing a foundation for next-generation financial technology infrastructure.
