PROFESSIONAL EXPERIENCE

Confidential, Brooklyn, NY

J2EE Developer

Responsibilities:

• Performed efficient delivery of code based on principles of Test-Driven Development (TDD) and continuous integration to keep in line with Agile Software Methodology principles.
• Implemented Java 11+ features like Lambda, filters and Predicates for adding functionality processing capability and Stream API to facilitate pipeline processing and method to eliminate elements based on the criteria.
• Used spring cloud as config service we have kept the all the config details like authentication and path info in it.
• Worked extensively on developing controllers, Interfaces and implementation classes using Spring Boot, Spring Cloud and Rest.
• Implemented Microservices for distributing different responsibilities of the system into different services for enhancing cohesion and for reduce coupling.
• Used AWS SQS to manage message queuing service that makes it easy to decouple and scale Microservices, and serverless applications and Communication with External Services.
• Dealt with latest features of Java 11 reading and writing to/from the files by using newly introduced methods.
• Provided cloud environment for Microservices using spring cloud Netflix (Eureka server).
• Implemented REST based web services using for JAX-RS and JAX-WS respectively.
• Used WebLogic as the app server for deploying the applications and Used JDBC as the data access layer connecting to Oracle DB.
• Used REST Client and POSTMAN to test the rest-based services and used JUnit and Mockito to test the middleware services.
• Creating and managing builds using Jenkins for CI/CD and use pipeline plug-in for managing multi project jobs effectively.
• Used Maven to acquire the dependencies and build the application. Used GitHub as a Version control & source code management
• Used JIRA as the bug tracking system to track and maintain the history of bugs/issues on an everyday basis.
