Engineer Software

Professional Experience

Firmware Engineer Level IV, International Game Technology - Systems Division, Las Vegas, Nevada.

May 2000 - July 2007.

Primary responsibilities as a Firmware Engineer included the project development, project design, code development and

installation of touch screen casino player tracking firmware and hardware.

Completed software development and system integration on an interactive touch screen Player Tracking device based on an ARM

processor with a WinCE RTOS using C and C++. Developed and verified PXA270 on chip peripheral interfaces, integrated new

features as well as porting of existing code from on an earlier iteration of the device, which also ran a multithreaded application on a

WinCE RTOS.

Completed a firmware enhancement on an 8051 controller based player tracking unit written in Assembly to add a cashless feature

incorporating smart card technology with secure authentication and communication for monetary transactions with gaming machines

and using a proprietary communication protocol.

Wrote a firmware upgrade in C for an Intel 80296 based product by analyzing and bridging between an overseas regulatory protocol

and Gaming Control Board (GCB) protocol, also upgraded the software power management and communication modules on a PIC

processer on the same hardware.

Designed and wrote a production test application using C++ for testing and recording failure conditions during final assembly and

testing of player tracking units.

Part of a team that authored a game security device patent: US patent 6641484.

Software QA Engineer, Bally Gaming, Las Vegas, Nevada.

November 1998 - April 2000.

Developed regression test software and hardware equipment, to test video game machine accounting and functionality using a

scripted language. The automated testing carried out verification of pay table accuracy, game functionality and system

communication for event messages.

Firmware Engineer, Hubbell Industrial Controls Madison, Ohio.

January 1997 - October 1998.

Developed firmware to monitor power quality on a Transfer switch control device written in assembly using a Microchip PIC

processor. The device used signal phase and amplitude difference to monitor both preferred and emergency power sources on a 3

phase or single phase system that enabled dependable transfer of power between the two sources during out of parameter

frequency (@ 50, 60, 400 Hz) or voltage level fluctuations(110-415 volts). Developed and documented test scenarios such as

testing under different environmental conditions, and documented the results as required for UL certification of the transfer switch.

Redesigned and enhanced a fire pump controller utilizing state machine methodology to add additional functionality for onsite fault

analysis.
