Developed Java 21 and Spring Boot microservices for financial transaction processing at extreme scale, supporting infrastructure handling 5B+ events daily and reducing transaction processing latency by 36%. Built distributed ledger services for double-entry accounting with reconciliation and immutable journal entries to improve financial data integrity. Engineered high-throughput payment processing APIs using Java, Spring Boot, Kafka, PostgreSQL, and Redis, reducing backend response latency by 31%. Implemented secure REST APIs and integrations using Spring Security, OAuth 2.0, JWT, OpenAPI, and GraphQL. Designed event-driven microservices with Kafka, Saga pattern, CQRS, DDD, idempotency, retries, and distributed consistency. Deployed on AWS EKS using Docker, Kubernetes, Helm, EC2, IAM, S3, CloudWatch, and Terraform; automated CI/CD with Jenkins, GitHub, Maven, Docker, and Kubernetes; improved observability with Prometheus/Grafana and OpenTelemetry.

Built Java 17 and Spring Boot microservices for production planning and inventory workflows used across 300+ manufacturing sites, improving API response latency by 34% using Redis caching and SQL optimization. Engineered backend services with Java, Spring MVC, Spring Data JPA, Hibernate, PostgreSQL, and REST APIs to increase transaction throughput by 29% while maintaining high availability. Developed React and TypeScript dashboards for machine monitoring and warehouse operations for 5,000+ plant operators, reducing dashboard load time by 41%. Created cloud-native microservices using Spring Cloud, Eureka, Config Server, API Gateway, OpenFeign, Kafka, and RabbitMQ. Delivered secure REST/gRPC services with Spring Security, OAuth2, JWT, Keycloak, and GraphQL. Containerized services with Docker and deployed to AWS EKS on Kubernetes/Helm. Automated CI/CD using Jenkins, GitHub, Maven, SonarQube, and JUnit 5; optimized AWS infrastructure with EC2/RDS/S3/CloudWatch/IAM. Built event-driven servi
