J2EE Developer

Responsibilities:

• Worked with business teams on requirements gathering and estimating the efforts for development using agile methodology.
• Migrated the coded from Java 8 to brand new version of Java i.e., Java 11.
• Utilizing Java 11 with feature var to create and store objects, Java 8 features Lambda expressions, Stream APIs, Optional class, Method references, for each method and Date/Time APIs.
• Designed and developed Micro Services business components using Spring Boot.
• Connected to Data sources and performed operations using Spring Data Framework features like Spring JDBC and Spring ORM.
• Observable Patterns are used for connecting to external API’s and subscribe to receive data with the help of RxJS libraries,
• Implemented OAUTH 2 (Rest service authentication) in our application in order to communicate securely with other protected resources by exchanging access tokens for authentication instead of using user name and passwords.
• Configured Package.json for application dev and deployment dependencies and used Node NPM to set it up.
• Developed the Code in Visual Studio and deployed application on Apache Tomcat Server.
• Using MongoDB to store and querying for the data and Composed and executed MongoDB scripts to insert.
• Configured internode communication between MongoDB nodes and client using SSL encryption.
• Setting up and configuring AWS's EMR Clusters and used Amazon IAM to grant fine-grained access to AWS resources to users.
• Automated CI/CD with Jenkins, build-pipeline-plugin, Maven, GIT Set up Jenkins’s master/slave to distribute builds on salve nodes.
• Used JIRA for defect management and to keep track of bugs and issues.
