Architected and developed scalable microservices using Spring Boot and Java 17, leveraging records and sealed classes for cleaner domain modeling. Secured enterprise applications with JWT, OAuth2, and Spring Security, enforcing RBAC and API gateway-level authentication. Modernized legacy apps by migrating codebases from Java 8 to 11/17, improving performance and maintainability. Automated CI/CD pipelines using Jenkins, GitHub Actions, and Maven, enabling zero-downtime deployments to cloud infrastructure. Led AWS/Azure cloud adoption, deploying containerized apps via ECS, AKS, Terraform, and managed services like Lambda, RDS, and API Gateway. Enhanced data pipelines and ETL using AWS Glue, Kafka, and Spark Streaming for real-time analytics and reporting. Implemented caching strategies with Redis and Spring Cache to reduce DB load and increase application throughput. Improved API performance and observability using Spring Boot Actuator, GraphQL, and Kibana dashboards. Practiced TDD/BDD with JUnit, TestNG, Jest, Selenium, and Cucumber, ensuring code reliability and continuous delivery.

Built microservices with Spring Boot, using Spring MVC, REST APIs, and Spring Security for secure backend logic. Migrated codebase to Java 11, refactored using Streams, Lambdas, and improved HTTP Client for modern performance. Implemented Kafka pipelines and integrated Spark Streaming to process real-time patient activity data feeds. Developed GraphQL and REST APIs for flexible frontend communication, reducing over-fetching and improving load time. Orchestrated container deployment via Docker, Jenkins, and Kubernetes (AKS), enabling scalable CI/CD workflows. Configured Azure API Gateway and Logic Apps for secure API routing, automation, and system interoperability. Integrated PostgreSQL and MongoDB using Hibernate and Spring Data JPA for transactional and NoSQL operations. Applied Apache Camel for API mediation and event-driven integrations across hospital and partner systems. Developed unit/integration tests using Jest, Enzyme, Selenium, and enforced TDD for high code coverage and reliability.

Delivered functionality iteratively using Agile/SCRUM, collaborating across sprints for continuous development and QA. Built microservices using Spring Boot and REST APIs, integrating secure backend logic with user-facing components. Enhanced user experience via AJAX, jQuery, and React-Draggable, enabling real-time interactivity and drag-drop features. Enforced role-based access with Spring Security and developed robust authentication layers. Created REST APIs using Jersey, implemented business logic in Java, and persisted data using Hibernate ORM. Employed Mountebank for mocking service dependencies to support parallel development and test automation. Built and deployed apps on WebSphere using Maven, Jenkins pipelines, and managed build artifacts (EAR files). Developed AWS Lambda functions to trigger internal APIs via API Gateway, and configured EC2, S3, and EBS. Leveraged Gulp for JavaScript minification/bundling and used Tortoise Git for code versioning and team collaboration.

Designed microservices using Spring Boot, Zuul, Eureka, and REST/SOAP APIs for case management, licensing, and service requests. Developed responsive SPAs using AngularJS, Bootstrap, and HTML5 to support real-time citizen interaction and agency workflows. Integrated Swagger/OpenAPI for automated API documentation and version control across microservices. Migrated applications from Cloud Foundry to AWS, using CLI/SDKs for deployment and CI/CD pipeline integration via Jenkins. Implemented secure service-to-service communication using SSO and Base64-based authentication via custom Node.js modules. Used Bonita BPM to build complex workflows with REST connectors, human task forms, and Groovy scripts. Developed scalable data pipelines and ETL frameworks using AWS Lambda, API Gateway, and structured/unstructured datasets. Built Kafka-based messaging services to handle real-time event processing between microservices and external teams. Created test automation using Selenium, TestNG, and Apache POI, enabling cross-browser regression testing. Wrote unit/integration tests with JUnit/Mockito, configured logging via Log4j2, and supported production/UAT issue resolution.

Project Summary: Contributed to the development and optimization of Saks OFF 5TH’s e-commerce platform, focusing on scalable backend services for inventory, orders, and product catalogs.
