PROFESSIONAL EXPERIENCE

Confidential, Dallas, TX

Java/J2EE Developer

Responsibilities:

• Involved in all phases of Software Development Life Cycle (SDLC) like Analysis, Design, Code DevelSpriopment and Implementation.
• Implemented Model View Controller (MVC) architecture through Struts at the Web tier level to isolate each layer of the application to avoid the complexity of integration and ease of maintenance.
• Developed the middle tier using Session Bean, Entity Bean/DAO and Business Objects.
• Developed Java interfaces for different function calls which convert the web services calls into EJB calls to the legacy system.
• Used Exception Handling and Collections API to implement various features and enhancements.
• Worked in multithreading environment by using different concepts like Thread Synchronization, Thread Deadlock and Inter communication.
• Developed using simple struts validation for validating user input as per the business logic and initial data loading.
• Used Hibernate to retrieve/update the data from/to the database.
• Developed multi-threading part in backend components.
• Developed supporting Java classes that controlled the whole flow of the module as per specifications.
• Implemented Form Classes, Action Classes for the entire application domain module using Struts framework.
• Used Spring Framework for Dependency injection and integrated with the using annotations.
• Involved in implementation of the presentation layer (GUI) for the application using HTML, CSS and JavaScript.
• Used multithreading for writing the collector parser and distributor process, which was getting Realtime data from zacks API in format of JSON, using multithreading improved the performance by a lot, using concurrency package of collections made it thread safe.
