• Led backend development with Spring Boot, Hibernate, MySQL and JPA, integrating key Springtechnologies (MVC, Security, Data and RESTful Webservices) for optimized functionality.• Developed a shell script for automating Nexus repository cleanup process via REST, deleting specified artifacts or those older than six months, reducing manual artifacts removal one at a time effort by 90%.• Optimized IBM WebSphere application and Nexus Repository deployment through CI/CD pipeline and implemented an auto-deployment folder, resulting in a 25% reduction in manual configurations and deployment time and improved efficiency by 10%.• Implemented Java and Cucumber automated testing, reducing manual testing time by 50%. Developed a reusable framework with Maven for seamless integration, ensuring codebase optimization through refactoring, reducing redundancy, and comprehensive reviews.• Performed POCs and case studies to evaluate integrating Reactive programming into the existingcodebase, reducing blocking code time by 30%.• Streamlined configuration data retrieval in a Banking project by consolidating 20+ APIs into a single Spring service, resulting in a significant 15-day reduction in manual effort and substantial time savings.• Independently developed the gateway policy using Axway Policy Studio and related components. Additionally, gained practical experience with WireMock and AWS services like EC2 and S3 bucket.• Acquired hands-on experience with syft and CycloneDX while working on generating a Software Bill of Materials (SBOM) to identify vulnerable components utilized in the project.

• Executed a comprehensive migration project, upgrading the system from Java 7 to Java 11, andtransitioning from SOAP to RESTful services. This initiative resulted in a more modern, clean, and easily maintainable codebase aligned with current industry standards.• Key contributor to backend development, specializing in REST and SOAP-based applications. Utilizedtechnologies including Spring Boot, Hibernate, JDBC, JAX-WS, MySQL, and JPA to design, implement, and maintain robust business logic.• Utilized Swagger for API documentation, Log4j for logging, and Git/GitLab for version control. Developed robust test cases with JUnit and Mockito, ensuring system functionality and reliability through detailed request/response validation against XML Schema during API testing with Postmanand service testing with SOAPUI.• Significant contributor to the development of a Java-based Selenium application for comprehensivecross-browser automation testing.• Automated environment control using custom Bash scripts, achieving a significant 50% reduction inprocessing time and enhancing workflow efficiency.

design and development of a comprehensive model for the Communication Navigation and Surveillance (CNS) System, crucial to optimizing message transmission among the three primary wings of the Airports Authority of India (AAI). This system played a pivotal role in enhancing the efficiency, reliability, and security of communications across multiple subsystems, directly contributing to the operational effectiveness of AAI.
