• Developing core payment microservices for PayTo functionality using Java 17, Spring Boot, and RESTful microservices architecture, integrated with the New Payments Platform (NPP) and the Mandate Management System (MMS) to enable secure, real-time mandate payments for Australian customers. Supporting financial messaging standards such as SWIFT, PACS, and PAIN.
• Working with Kafka for event-driven communication, AWS for cloud-native deployments, and Harness for managing CI/CD pipelines to ensure reliable and automated delivery.
• Implemented dynamic password rotation in microservices using HashiCorp Vault, eliminating the need for manual restarts when passwords rotate every 90 days, resulting in a more robust and reliable application.
• Integrated Resilience4j to add retry and fallback mechanisms, improving system stability and fault tolerance in production-grade backend services. Migrated microservices from Java 11 to Java 17 to maintain security compliance.
• Enhanced observability and traceability by introducing correlation and tracking IDs in logs using MDC (Mapped Diagnostic Context) across batch processing and notification services.
• Implemented graceful shutdown for microservices to ensure safe pod terminations and maintain data integrity during deployments. Built a scheduler to automatically reprocess failed database records, improving system reliability.
• Developed comprehensive JUnit test cases to maintain strong unit test coverage and support maintainable, production-ready code.
