PROFESSIONAL EXPERIENCE

Confidential, Wayne, NJ

J2EE Developer

Responsibilities:

• Actively involved in all phases of Software Development Life Cycle (SDLC) like Analysis, Design, Development, System Testing and User Acceptance Testing.
• Implemented Spring framework using Spring Boot, Spring-AOP, Spring-ORM, Spring-JPA, Spring-Data, Spring-Security modules.
• Developed and consumed Rest Services using HTTP methods such as GET, POST, PUT, and Delete for user and account Microservices.
• Dealt with latest Java 11 features like utility methods, local-Variable Syntax for Lambda Parameters, Nested Based Access Control and Reading/Writing Strings to and from the Files.
• Developed application layer and business logic using Spring Boot to deploy them as microservices and used Spring Core Annotations for Dependency Injection and Spring Batch for running Batch jobs.
• Designed and developed asynchronous RESTful Micro services using Spring boot 2.2 that are consumed by other micro services with an average response time of 30 milliseconds.
• Adopted AWS IAM for authentication information management, such as username/password and access-token. Deployed the authorization and authentication module on AWS EC2
• Implemented user microservice for user account management (user account login/registration) using Spring Boot, Spring Security, and Spring Cloud.
• Used Spring IOC for dependency injection and make the application loosely coupled and Spring AOP for logging purposes.
• Wrote database triggers, procedures, functions in PL/SQL and incorporated business rules and constraints.
• Worked with JUnit Regression Test Framework to implement unit testing, to accelerate programming speed and to increase the quality of code.
• Secured API's by implementing OAuth 2.0 token-based authentication/authorization using Spring Security.
• Carried out responsibility of delivering the tasks including database scripts, source code and any other documents as and when required through GitHub.
• Prepare and Implement Project Plan using JIRA tool, it is the central point where all the work allocations and status updates are maintained.
