Responsibilities:

• Involved in various phases like design and development of Software Development Life Cycle (SDLC) and the project was developed using Waterfall methodology, which is migrated to Agile methodology.
• Developed detailed use case diagrams and sequence diagrams using IBM Rational Application Developer UML Visualization to express the detail design in elaboration phase.
• Performed requirement gathering, analysis and design of the solution ensuring integrity of the data transferred between BCBSM systems.
• Trained and mentored the members on the team while working on multiple Applications simultaneously.
• Worked on multiple Web Applications in the Project which were based on Frameworks Spring with AngularJS Library or JSF Library.
• Developed a view layer using JSP, AJAX, JSTL, and JavaScript.
• Extensively used AJAX technology to add interactivity to web pages.
• Primarily worked on a Batch Application using multithreaded programming for parallelism and achieved faster overall execution
• Employed JPA 2.x to store the persistent data as an Object Relational-Mapping (ORM) tool for communicating with the database for Web Applications and JDBC to access the Database in Batch Applications.
• Configured persistence configuration xml files and developed POJO’s to map Objects to Oracle relational database.
• Generated Java/J2EE design patterns like Singleton, MVC, Factory, Command, Data Transfer Object, and Service Locator. This facilitates clean distribution of roles and responsibilities across various layers of processing.
• Used IBM RAD for developing the projects.
• Created and implemented Oracle Stored Procedures, functions, and triggers and improved performance by embedding logic as single execution plan on the server.
