Java Developer at Citi Bank

January 1, 2025 - Present

Modernized the loan origination platform by migrating monolithic modules to Spring Boot microservices. Refactored backend logic with Java, REST APIs, and Spring Data JPA; leveraged Streams and robust exception handling to improve code quality and reduce processing time. Worked on microservices for KYC, document verification, and underwriting, integrating PostgreSQL for persistence and Feign for inter-service calls, with Swagger documentation. Implemented Spring Security with OAuth2 and JWT for authentication/authorization, and enhanced logging/monitoring via AWS CloudWatch with RBAC across multiple services. Assisted in Dockerizing services and preparing for AWS ECS deployment; contributed to CI/CD pipelines and deployment reviews for 99.9% uptime. Version control with Git, feature branch management, and peer reviews; built packages with Maven/Gradle to support Jenkins-based CI.

Java Developer at Novartis (India)

July 1, 2023 - October 14, 2025

Designed and developed backend microservices in Java (8, 11, 17) using Spring Boot and Spring Cloud to ensure high availability and scalability of inventory and procurement modules. Implemented RESTful APIs for supplier management, procurement workflows, and inventory tracking with robust exception handling, multithreading, and connection pooling. Used Hibernate/Spring Data JPA with PostgreSQL and Oracle, applying advanced indexing, partitioning, and strict ACID transaction management. Integrated Apache Kafka for real-time stock updates and notifications, linking pipelines with Azure Event Hubs for monitoring. Built SAP ERP integrations via SAP APIs to sync procurement and invoicing, reducing manual data handling by 85%. Wrote extensive unit/integration tests (JUnit, Mockito) achieving high test coverage. Implemented CI/CD pipelines (Jenkins, Azure DevOps) deploying containerized microservices to AKS with rolling updates and auto-scaling for 99.9% uptime. Monitored with CloudWatch/Prom
