- Designed changes for CSR application - Generate test cases and scenarios- Follow System Development Methodology- Used mainframe CICS transaction calls through CallFlow agent predecessor to MQ-Series.- Modified Visual Basic application that interface with mainframe CICS through CallFlow.- Modified DB2 tables and applications used in the CSR application.- Modified small Java Struts Web applications to add additional call center pages in JavaScript and CSS.- Created new Java tags to be used by the Web design team.Projects at Blue Cross Blue Shield as a contractor- Project #1 – Enhanced existing Java struts applications to include new data. The data was stored in a Oracle database. Several new tags were created to allow the web page designers use the data in several other web applications.- Project #2 - Enhanced Visual Basic application to include new data. The application uses a product called CallFlow which is a predecessor to MQ series to execute CICS transactions on the mainframe and passes the data in a message down to the VB application.

º Assisted users departments in determining Lawson upgrade impacts and new processes.º Create programs in Micorfocus COBOL, Lawson 4GL, PL/SQL, Unix Script, Perl and Java.º Implemented and Supported Lawson Financial applications version 8.1 with hundreds of customized Lawson programs and reports.º Designed and coded changes to custom interface processes that moved data to and from external systems using Perl web services.º Designed database conversion process in Perl to convert from Lawson data version 7.24 to 8.1. The Pulte database was to big to convert using Lawson tools so I designed a custom conversion using multi-threaded Perl scripts.º Converted complex Perl and Perl CGI scripts on UNIX to Java and PL/SQL programs to streamline shared code between web and batch interfaces.º Converted custom Perl CGI web applications to the new version of Lawson data structure.º Designed and modified web pages using HTML and Java script that provide a non-Lawson interface to Lawson data.º Designed and modified Perl CGI web services interfaces to external system.Projects at Pulte Homes:º Designed and modified web applications using Perl CGI scripts, HTML, and Java script. Most of these web applications enhanced or replaced Lawson standard screens.º Designed and modified web services scripts built from Perl CGI scripts. These services exchanged data between Lawson and external systems and vendors.º Lawson implementation has major modifications and new custom programs in Microfocus Cobol and Lawson 4GL. As part of the process, data is extracted from Lawson or loaded into Lawson using XML messages. The original implementation the process was written in 300 Unix Perl scripts. These scripts were poorly structured and difficult to support. This project redesigned the scripts into Java batch applications, PL/SQL stored procedures, and well structured web service calls.
