WebSphere Developer/Admin, Confidential

Developed portions of the e-commerce portal IBX.com using HMTL, JavaScript, Java, DB2 UDB, Oracle, Policy Director, and WebSphere Studio products. Worked on a team that designed and implemented the portals for IBX.com. The member, provider, and group portals were designed in a rapid application development environment in order to meet a strict deadline. Gathered and developed the business requirements for the IBX.com project as a member of the requirements gathering team. There was no pre-existing e-commerce functionality in the previous version of IBX.com and so most of the development was done from business requirements, which I helped to develop. The design and implementation was completed on schedule. Designed a web application that merged the functions of three applications into one. Two applications were mainframe-based applications and the third one was a Powerbuilder application. The purpose of this was to reduce the phone time that the customer service reps spent on the phone with doctor’s offices. The final application was a web interface that was integrated into the Powerbuilder application that had all the functionality in order to increase employee productivity. I received an award for this project, which is in my HR record at the company. The technology used with this application was WebSphere Studio Application Developer 4.0 (Java, J2EE, JSP, JavaScript, HTML), XML, Struts, Winsql, PVCS, Client Access Express, and Oracle. Developed a Java struts application to replace some existing mainframe functionality for the customer service reps. The purpose of the project was to make a more user-friendly application than the existing mainframe based applications that several departments were using. This greatly reduced call time of the service reps and training time for new reps. Also new business logic was added into the new application to improve productivity. The technology and skills used in the project were WebSphere Studio Application Developer 4.0 (Java, J2EE, JSP, JavaScript, HTML), XML, Struts, PVCS, Winsql, Client Access Express, and Oracle.
