SUMMARY:
Over 15 years of experience in software engineering and information technology, working on distribution,
manufacturing and ERP systems. Degrees in computer science and mathematics. Demonstrated expertise
in robust development strategies, efficient algorithm design, client-server architecture and relational
databases. Proficiency in data analysis and relevant areas of applied & discrete mathematics.
PROFESSIONAL EXPERIENCE:
Applications Engineer 11/2010 – present
Levi Strauss & Co.; Hebron, KY
Logistics – Applications Services
Responsibilities
Maintain, troubleshoot, modify and enhance applications in primary software systems used in Levi’s
distribution centers.
Systems
 Workload Management System - Custom system for planning and monitoring workflow through the
distribution center; Client-server architecture on an HP-UX server with an Oracle database and
PowerBuilder GUI clients; Server functionality implemented in daemon processes communicating via
TCP/IP sockets, written in C/C++ with Oracle Pro*C embedded SQL, and supplemented by PL/SQL
stored packages, procedures, functions and triggers.
 Transportation Management System - Custom transportation system with the same architecture as
Workload, communicating with it via TCP/IP sockets and interface tables using Oracle database links.
 Mandate Warehouse Control System - Material handling system from CASI written in “C” that runs on
a distributed network of QNX nodes (microkernel OS for real-time systems); Communicates with
Workload through TCP/IP sockets and NFS mount file exchanges.
 Red Prairie (JDA) Warehouse Management System - 3rd
party WMS based on a proprietary service-
oriented architecture (SOA) called MOCA; Developed Data Driven Application (DDA) GUI screens,
RPwriter reports, RP Integrator transactions, application triggers, custom MOCA commands, and
command/component overrides for site-specific functionality.
Lead Software Development Engineer 03/1998 – 02/2009
GAP, Inc.; Erlanger, KY
Supply Chain IT Division (SCIT)
Responsibilities
Design, develop, enhance, repair and debug applications for the Warehouse Management System (WMS);
Technical consultant during requirements gathering and functional design of system enhancements;
Determine estimates of development effort for project planning; Compose technical design
documentation; Design and modify database schema objects; Devise SQL queries for data analysis and
reporting; Plan, execute and interpret results of system stress tests.
System Architecture
Client-server architecture hosted on an HP-UX server with an Oracle database; Programs written in “C”
with Oracle Pro*C embedded SQL, supplemented by PL/SQL stored packages, procedures, functions and
triggers; Server functionality implemented in daemon processes communicating via UNIX IPC
mechanisms (message queues, shared memory, signals, sockets).

2. Key Projects
 Interfaced WMS with a Labor Tracking module from Red Prairie/JDA Software. Developed
supporting functions, identified functional trigger points in the WMS application, and inserted the
appropriate hooks for the collection and transmission of relevant job/assignment attributes.
 Integrated a planning optimization module from Advanced Process Combinatorics, Inc. with the WMS
allocation wave planning process. Introduced a new method for parsing and processing hierarchical
interface files by modeling the basic control structure after a finite state machine (FSM).
 Researched WMS interprocess message traffic issues (bottlenecks, race conditions and deadlocks) by
recording operations performed on message queues. Instrumented message handling routines to log
relevant information, and developed tools to load raw log data into database tables for query analysis.
 Worked on a dynamically (i.e. compile-time) generated “CRUD” library of common application
database operations. The generating utilities use the schema data dictionary and a set of configurable
rules to generate Pro*C embedded SQL data access routines and accompanying build scripts.
 Formalized aspects of the application framework: designed routines and tables to maintain system
parameter settings in the database, coordinated with their shared memory counterparts. Also, created
more robust routines and data structures for accessing environment variables - to ensure a complete
snapshot of the process environment at startup.
Software Engineer 11/1994 - 03/1998
American Computer Technology / Computer Creations Inc; Cincinnati, OH
Responsibilities
Design, develop, enhance and troubleshoot applications for an accounting & manufacturing (ERP/MRP)
system called ShopTrac; Develop and maintain customizations for clients; Perform system installations,
upgrades, and data conversions; Participate in requirements analysis, functional design and customer
training.
Key Project
Developed a job scheduling module for a printing company, which implemented a “Backward Finite
Scheduling” heuristic used in process manufacturing. This expert system was used to minimize time,
labor and materials associated with equipment setup and changeover, and maximize dollar-volume
throughput, within the constraints of machine capacity and job deadlines.
Graduate Teaching Assistant 09/1992 - 06/1994
University of Cincinnati, Department of Computer Science; Cincinnati, OH
Responsibilities
Teach undergraduate computer science courses, which entailed: lecturing; devising and grading
assignments, quizzes & exams; running lab sections; assisting students during office hours.
Programmer/Analyst 05/1991 - 01/1992
Cincinnati Bell Information Systems; Cincinnati, OH
Responsibilities
Plan, execute and document integration testing of batch and online programs for a telecommunications
billing system.

University of Dayton Research Institute; Dayton, OH
Responsibilities
Assist engineers with various research projects; Develop FORTRAN and SAS programs to perform
mathematical/engineering computations and statistically analyze significant volumes of empirical data.
