Collaborated with a team of developers to design, develop, and deploy web applications using Java, Spring Framework, and Angular.Implemented RESTful APIs to enable seamless integration between front-end and back-end systems.Participated in code reviews and conducted unit testing to ensure the quality and reliability of the developed software.Worked closely with business analysts and stakeholders to gather requirements and translate them into technical specifications.Optimized application performance through code refactoring, database tuning, and caching techniques.Implemented security measures, including authentication and authorization mechanisms, to safeguard sensitive data.Conducted troubleshooting and resolved technical issues reported by users, ensuring minimal downtime.Collaborated with cross-functional teams, including UX/UI designers and quality assurance engineers, to deliver user-friendly and bug-free applications.Actively participated in Agile development methodologies, including daily stand-ups, sprint planning, and retrospective meetings.Worked on Splunk dashboards, alerts generation, and Email notifications.Conducted code reviews and provided constructive feedback to improve code quality and maintainability.

Optimized cleaning up of session-level Data Structure and shared across different open tabs when data is flushed/committed from one of the tabs.Implemented Struts encouraging application architectures based on the Model View Controller (MVC) design pattern and Struts 2 framework for front-end development and presentation logic. Developed JavaScript for all client-side validations and developed GUI using CSS, JSTL, and XSL. Apply focused development changes across oracle databases and see the changes applied through the life cycle of environments and testing into production via internal deployment tool. Define requirements and specifications for Development using Oracle R12, Oracle Forms, Oracle Reports and SQL. Web pack module bundler and Babel JavaScript compilers used to accompany React JS. Implemented Spring Boot to create a CRUD back-end for our React-frontend application. Worked with Jenkins Continuous Integration and Continuous Deployment (CI/CD).

Security vulnerability fixes on server by setting up Big-Fix, Carbon-Black, Flex-era on cloud VM, Configuring firewall settings in Google cloud platform.Developed classes using Core Java/Executor Service (multithreading, concurrency, memory management) consumed REST Web Services for getting the credit card information from third party application using EME.Worked on Docker and Kubernetes on cloud providers, from helping developers build and containerize their application (CI/CD) to deploying either on public or private cloud.Used the fundamentals of Java features like parallel streams and filters along with multithreading used smoke tests, for functional unit and integration tests on all major system components.Converted a monolithic app to micro services architecture with spring 4.x using 12 factor app methodology and deployed, Scaled, Configured the wrote manifest file for various Micro services.Implemented Spring Circuit breaker pattern, Integrated Hystrix Dashboard to monitor Spring Microservices used Git as Version Control System for the application.Utilized Java Lambda feature to implement business logic JBPM is a lightweight, extensible workflow engine written in pure Java that allows you to execute business processes using the latest BPMN 2.0 specification.
