## BIO •Designed and implemented the back end processing system for a web utilization reporting system. The system utilizes DB2, Perl, and SQL. XML data is loaded using perl processes running in parallel to maximize performance. That data is then post processed by a collection of stored procedures prior to delivery to the web server for customer display. •Wrote a Perl/CGI API and library to interface web based applications with a third party graphing package written in Java. •Implemented a new C sorting subroutine for the Thomson suite of online search products reducing sort times of large record sets from as much as several minutes to less than one second. •Reengineered data delivery process using a propriety format to one using XML. Oracle database, XML, and XSLT tools were critical to the success of this project. •Wrote the data transfer component of Methodsfinder, a web based application providing experimental methods to the life sciences community. This component was a Perl/DBI interface used to extract, transform, data from an Oracle 9i database using stored procedures, views, and functions to manage complex queries. •Modeled using Rational Rose UML tool and wrote in C++ components of a telecommunication billing system. •Designed and wrote a search and filter system for a brokerage desktop system allowing customers to perform ad-hoc searches of their clients, holdings, and securities. •Developed Visual Basic and C applications to consolidate administration and delivery of data between Pep Boys stores, back office mainframe, Sybase 10 databases, and external data sources. •Wrote Visual Basic application enforcing data integrity and UPC format preventing any recurrence of this problem in the future. •Corrected a pervasive problem at Pep Boys where approximately 30% of Universal Product Codes in the cash register system were invalid. Developed tools to correct the existing data and implemented programs and procedures to prevent the problem from recurring. ## Area of Expertise C/C++, Perl, SQL, Java, XML/XSLT, Object Oriented Development, IBM UDB, Oracle DBMS, Rational Rose UML Suite, Linux, Windows.
