Develop new functionality and maintain existing functionality for the JAVA SWING application for the WARSIM constructive simulation. Utilize several types of design patterns to facilitate development and maintenance ( model view controller, Observer, Command). Lead small teams to design and implement new WARSIM functionality. Interfaced with CMP and JMPS to created C2 messages. Worked closely with government customers and military users. Traveled to South Korea to help train military on simulation. Developed in both Windows and Unix environment. Joint After Action Report System. Modify existing multi threaded JAVA application in a UNIX environment to be able to handle multiple kinds of simulation data. Manipulated Oracle database to add, delete, or modify database tables to ensure data being collected and stored properly. Create new JAVA applications to support new functionality. Also worked on the data collector and processor, which takes data from the simulation and put it into Blobs in the db, and subsequently takes that data and sorts and inserts the data into the appropriate database tables.

Developed, modified and tested a Java, multi-threaded application. Worked with Swing API to develop GUIs. Developed XML parsers to read XML data files into application. Developed tools to allow the users to create the actors for the simulations and saved data as XML files. Troubleshot/corrected simulation issues.; Gateway Responsibilities:

• Develops multi-tiered software using JAVA, J2EE, JSP, XML, XSL, SQL, JavaScript, HTML and DHTML technologies.
• Performed maintenance and new development on Oracle 9iAS portal application. Introduced and applied the concept of separating business logic from display logic. Removed database access from the JSPs and placed this business logic in separate java files. Added, deleted, and modified data from Oracle database.
• Participated on a team to convert the existing Oracle portal application to a multi-iframed web application that mimics a portal environment using XML, XSL, XSLT, JAVA, JSP, and JavaScript. Took initiative to learn XSL technology and then trained other team members. Used XSL and XSLT technology to create XML files from database and ultimately translate the data into useful web pages. Created stand-alone java application to generate a multi purpose calendar. Created servlets and servlets filters that employed both SAX and DOM XML processing. Created a JavaScript date/time selection component to facilitate user input.
