PROFESSIONAL EXPERIENCE

Confidential, Fairfax, VA

J2EE Developer

Responsibilities:

• Followed Agile methodologies to plan work for every iteration and used continuous integration tool to make the build passes before deploying the code to other environments.
• Implement Java 11 latest features like Lambda, filters and Predicates for adding functionality processing capability and Stream API
• Implemented Spring framework using Spring Boot, Spring-AOP, Spring-ORM, Spring-JPA, Spring-Data, Spring-Security modules.
• Decomposed existing monolithic code base into Spring Boot micro services. Developed new features and provided support for all Micro services.
• Used Spring Core annotations for Spring Dependency Injection, Spring MVC for Rest API’s and Spring Boot for microservices.
• Created RESTful services and end points within the Microservices architecture using Java/Spring Boot.
• Implemented OAuth2 token-based authorization scheme using spring security to secure Rest API.
• Implemented RESTful based web services using for JAX-RS.
• Worked on Tomcat for deployed interface modules and used Oracle for persist the data getting from external system
• Deployed the developed web components on Apache Tomcat Web-Server.
• Built Microservices using spring boot with continuous deployment and continuous integration using Jenkins.
• Used GitHub to maintain the version of the files and took the responsibility to do the code merges from branch to trunk and creating new branch when new feature implementation starts.
• Used JIRA tool for Issue/bug tracking, monitoring of work assignment in the system

J2EE Developer

Responsibilities:

• Involved in SDLC requirements gathering, analysis, design, development and testing of application developed using Agile methodology.
• Utilized Java 8 features like Lambda expressions for collection evaluation and comparing the data, Stream API for Bulk data operations on Collections which would increase the performance of the Application.
• Refactored existing monolithic application by identifying components that needs to be transformed to Micro- services architecture, with Spring Boot-based services interacting through a combination of REST.
• Developed Microservices architecture applications using Spring Boot, Spring Cloud config, and Restful Web Services.
• Responsible for maintaining and expanding AWS (Cloud Services) infrastructure using AWS (SNS, SQS).
• Implemented MVC architecture using Spring MVC and configured with service and persistent layers of the application. Used Spring IOC, AOP, Spring Boot to implement middle tier.
• Implemented various J2EE Design patterns like Singleton, Service Locator, Business Delegate, DAO, Transfer Object, and SOA.
• Used XML parser APIs such as JAXP (SAX) and JAXB in the web services request response data marshalling as well as unmarshalling process.
• Worked with Build Engineer on Maven Configuration to build the application and deployed on Tomcat Server.
• Used GIT to maintain the version of files and took the responsibility to do the code merging’s and creating a new branch when new feature implementations start.
• Used JIRA to assign, track, report and audit the issues in the application.
