Designed and enhanced a merchant settlement platform using Java 17, Spring Boot, and Spring MVC; built idempotent REST APIs and implemented saga-based orchestration for reliable same-day settlement cycles, reducing reconciliation backlog from T+2 to T+0 for priority merchants. Developed low-latency validation services with PostgreSQL and Resilience4j to sustain sub-120ms response times during peak traffic. Created secure internal portals for real-time settlement dashboards and provisioned infrastructure on AWS via Terraform.

Engineered cloud-native retail e-commerce microservices using Java 17, Spring Boot, and Hibernate for catalog, cart, order, and inventory; improved modularity and reduced inter-service coupling by 40%. Built frontend modules with React.js, TypeScript, Redux; reduced initial page load time by 32%. Architected asynchronous order orchestration with Apache Kafka and RabbitMQ; enhanced resiliency under peak load. Implemented CI/CD pipelines with Jenkins, Docker, and Kubernetes; established observability with Prometheus and Grafana; improved incident detection by 35%. Optimized persistence with Hibernate and Redis caching; led migration of legacy modules to containerized microservices on AWS, achieving ~$75K annual cost savings and 45% faster deployments. Secured APIs with Spring Security, JWT, OAuth 2.0; achieved 85%+ test coverage with JUnit 5 and Mockito.
