PROFESSIONAL EXPERIENCE

Confidential, KY

Java Developer

Responsibilities:

• Responsible for full life cycle development of three modules. This includes analysis, documentation, design, coding, testing. Understand and implement the application in STRUTS framework.
• The first module was to create the login procedure for the end the user.
• Designed and developed invoice presentment module which generate PDF document for users using iText.
• Involved in the detailed design of user interfaces and business layers. Extensively worked on struts.
• Used Struts tag library for implementing the user interfaces. Used Struts Validation Framework and JavaScript (extjs )for Client side validations.
