Confidential

J2EE Developer

Responsibilities:

• Worked in an Agile Environment and participated in various phases of Software Development Life Cycle (SDLC), including requirement gathering, modeling, analysis, architecture design, prototyping, developing and testing.
• Successfully converted legacy applications to Java 1.8 to utilize features such lambdas streams resulting in lowered supports cost, increased readability and performance.
• Developed application on spring framework by utilizing its features like Spring Dependency injection, Spring Transaction, Spring AOP with Spring MVC.
• Implemented (SOA) to retrieve data from client side and made REST API calls and parsed the data to client and handled the security and Authorization using Spring Security.
• Dockerized and deployed microservice via an AWS EC2 instance to maintain service-oriented architecture and reduce coupling among services.
• Parsing various format of files like XML, JSON format files and load into Oracle database with XML and JSON modules.
• Used Spring Batch as spring batch jobs can meet the requirements of reliability, robustness, and traceability, which are essential for automatic processing of large amount of data.
• Used Web services (REST) for transmission of large blocks of data over HTTP.
• Used Spring AOP for logging, auditing, transaction management to distinguish business logic from the cross-cutting concerns.
• Used JDBC to connect to the relational database and used Log4j for logging to trace the application log messages which is used for debugging.
• Used Maven as build automation tool which dynamically download the libraries or dependencies.
• Used Jenkins as build management tool for continuous integration process.
• Used JIRA tool for project management used in the application to tack bugs, issues and project management functions.
