Designed and developed scalable, distributed microservices using Spring Boot, Spring Cloud, Spring Security, Spring Data JPA, and REST APIs to support high-availability banking applications. Implemented event-driven communication with Apache Kafka, built API Gateway, Service Registry, and Config Server using Netflix OSS/Spring Cloud, and established centralized authentication with JWT/OAuth2, rate limiting, caching, and robust exception handling. Created CI/CD pipelines with Jenkins, GitHub Actions, and Docker; deployed containerized services on AWS (EC2, S3, RDS, Lambda) and Kubernetes (EKS); built React UI components and GraphQL endpoints; ensured accessibility and responsive design for enterprise UI; integrated with data stores (PostgreSQL, MySQL, MongoDB) and implemented end-to-end traceability and observability.

Led modernization of legacy banking/brokerage applications to cloud-native microservices using Spring Boot, Spring MVC, and Hibernate. Delivered RESTful and GraphQL APIs, implemented containerized deployments with Docker and Kubernetes on AWS/Azure, built Python microservices for orchestration with Kafka, SQS, DynamoDB, and Redis, and created Helm charts and Kubernetes manifests for multi-environment deployments. Collaborated with UI teams for Angular/React front-ends, implemented CI/CD pipelines, and ensured robust testing with JUnit/Mockito.

Developed cloud-enabled microservices using Spring Boot and React/Node.js, migrated legacy monoliths to REST-based services, and implemented Kafka-based data ingestion and real-time dashboards. Built Python AWS Lambda functions for serverless automation, integrated SAML/OAuth2 with Azure AD, and deployed on AKS/Azure. Contributed to CI/CD pipelines, implemented unit/integration tests, and optimized SQL/NoSQL queries for performance and scalability.
