I’m Pramodh, a Java Backend Engineer with 5+ years of experience building payment gateway and fintech infrastructure. I focus on real-time transaction processing, distributed microservices, and event-driven systems—especially in card payments and secure integrations using ISO 8583, EMVCo 3D Secure, and gateway platforms like CyberSource and MPGS. I’ve worked across high-throughput architectures using Apache Kafka and Redis to improve latency and transaction efficiency, while keeping systems secure and PCI DSS compliant through tokenization, TLS enforcement, and audit logging. I also have onsite MENA integration experience (UAE) delivering gateway connectivity for telecom billing, including digital wallet support and recurring payment flows.…I’m Pramodh, a Java Backend Engineer with 5+ years of experience building payment gateway and fintech infrastructure.
