Completed assignment at Merck as an independent consultant.
FIRST CONSULTING GROUP
Senior Consultant, System Development Services. October 1998 to May 2001
Merck, September 1999 to May 2001
• Developer/Analyst providing application development/support and mentoring. Created C/Pro*C and Oracle PL/SQL
programs for implementation in Merck's contract management system, GenCord. Participated in data modeling and
database design. Designed, developed, coded, and documented back-end on line transaction processing, back-end
batch processing, and back-end job scheduling system for the GenCord project.
• Performed various enhancements to Merck's contract management system using SQL Station, thus gaining extensive
experience in Oracle PL/SQL, application performance tuning and query optimization. Assignments included the
creation of new rebate processes, validation processing enhancements and enhancements to formulary processing.
• Mentored two Merck developers by providing guidance on various assignments, including development of reports and
validation processing. Delegated work assignments to these individuals.
Mortgage Management, Inc., April 1999 to July 1999
• Created the database and service for the database server, and maintained the database architecture for Mortgage
Management, a service provider of biweekly and bimonthly mortgages.
• Implemented database scripts and stored procedures. Development was performed using Sybase Data Architect and a
Sybase SQL Adaptive Server Anywhere version 6.0.1 database. The Data Model consists of a Sybase Data Architect
Conceptual and a physical Data Model. The physical Data Model is used to generate a physical Sybase SQL Adaptive
Server Anywhere database.
FCG’s Integrated Systems Consulting Group, October 1998 to February 1999
• As a member of the Charge Analyzer Group Editor (CAGE) development team, designed, coded, and wrote an
Enrichment Module for a billing system used by a Midwest Hospital. The Enrichment Module would serve to enrich
and validate charge data from an external billing system or other external sources.
• Enhancements were completed using Visual C++ 5.0, DB library C routines and with MSSQL residing on an NT
operating system, although it is fully portable to UNIX and Oracle. This application is remarkable in that it requires
only minimal changes in code to customize the module for new clients. Extreme object oriented abstraction and data
dictionary objects allowed the module to customize itself through changes in the data dictionary and INI files.
SANCHEZ COMPUTER ASSOCIATES
Programmer, July 1997 to October 1998
Provided application production support and development of the core banking software for retail banking institutions.
• Analyzed functional specifications to design and write technical specifications using a MUMPS database in a
VAX/VMS environment. Additional exposure to a client server application using Visual C++ and Windows sockets.
• Using Visual C++ and Windows sockets, created a multi-threaded client server application for the approval of ATM
transactions. To meet the required functionality of this program, created a remote interface between ATM machines
and the bank’s main database for the approval of monetary transactions. The client server code resided on an NT
operating system that received and transmitted data between two IP addresses. There were two aspects to the code.
The first is the socket portion using Microsoft Windows Sockets. This portion of the code handled basic messaging
processing to and from IP addresses. The second aspect of the code dealt with the volume of messaging being
transmitted. This required creating a queue class for incoming messages. To take advantage of the queue class it was
necessary to make use of the multi-threading and synchronization capabilities within Visual C++.
• Enhanced deposit and loan application system to calculate interest accrual based on a client-defined matrix using a
MUMPS database.

COMPETITIVE MEDIA REPORTING
Programmer Analyst, September 1994 to July 1997
Designed, developed, and provided application production support for in-house software used to monitor media
advertisement data via multiple delivery methods.
• Developed a data feed process for the StrADegy data warehouse transferring flat file data, which was translated and
enhanced in preparation for delivery to the client. The required functionality of this process was to take occurrence
and master data to create a de-normalized database of fact tables from these two sets of data and then create
dimension tables based upon the fact tables adhering to a Star Schema data warehouse design. The StrADegy data
feed process is a server application spread across two operating systems with the bulk of the code written in Sybase
embedded SQL within the C language. The process is driven by DCL and KORN shell scripts with the emphasis of
the scripts written in KORN shell. The major functionality of the scripts is for calling C programs, error processing
and messaging.
• Modified and enhanced the Productionization project to allow for performance tuning and the optimization of
existing code. The Productionization project was a conversion of the existing software from Ingres5 to Ingres6 with
an emphasis placed on efficiency and reliability. The majority of the code was written in DCL scripts and embedded
SQL within the C language. Error trapping was provided by the C programs and reporting of errors was
communicated via the DCL scripts.
• Provided documentation for all code related to project.
• Performed help desk support functions including problem analysis, identification, and resolution.
• Development was performed using DCL, KORN shell scripting, Multinet FTP, Sybase, Open Client, Ingres 5, Ingres
6, DCL and embedded SQL within C in VAX/VMS cluster and UNIX operating environments.
