J2EE Developer

Responsibilities:

• Participated in various phases of Software Development Life Cycle (SDLC) using Agile Methodology and followed Scrum sessions.
• Used Java 11 new utility Methods in string class like isBlank(), lines(), trip(), stripLeading(), stripTrailing(), and repeat(int).
• Involved in developing Application Components with Spring, Spring Boot, and Spring Data.
• Created Restful web service by using JAX - RS and implemented authentication by using OAuth2 Security Framework.
• 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.
• Implemented Microservices architecture using Spring Boot for making application smaller and independent.
• Worked on database interaction layer for insertions, updating and retrieval operations of data from oracle database by writing SQL queries.
• Created customized AMIs based on already existing AWS EC2 instances by using create image functionality, hence using this snapshot for disaster recovery
• Wrote build and deployed scripts using Maven and Maven scripts and involved in performance analysis of the application and fixed problems/suggest solutions.
• Used Jenkins as a Continuous integration tool for configuring and triggering the automation test suite executions
• Built the Application using Maven and deployed it on Apache Tomcat Server.
• Enabled Swagger for the application for better documentation purpose.
• Automated CI/CD with Jenkins, build-pipeline-plugin, Maven, GIT Set up Jenkins s master/slave to distribute builds on salve nodes.
• Used JIRA tool for project management used in the application to tack bugs, issues and project management functions.
