o Wrote hypertext manual for startup and trouble-shooting demonstration system.

January 1992 to May 1995:
* Embedded Hardware/firmware Developer:
o Designed and maintained switching fabric circuits (PCB, PWB) for Global System for Mobile communications (GSM) Speech Transcoding Frames (STF)
o Updated TDM bus protocol firmware and documentation for three Intel 8051 based circuit packs: Master Bus Control Unit (MBCU), Communication Interface Unit-LAPD (CIU-LAPD), and Communication Interface Unit SS7 (CIU-SS7)
o Wrote production and test code in ANSI "C" and assembly-language
* Firmware Representative to Change Management Review Board:
o Represented firmware developers on both the hardware and software modification request (MR) review boards, and supported the organization's successful effort to achieve ISO 9000 compliance.
o MRRB oversaw and synchronized changes to cellular base station hardware, firmware, call processing software, and documentation.

August 1990 to January 1992:
* Digital Hardware Developer:
o Successfully completed the design of a 0-wait-state 4 Mbyte (1Mx36) core memory unit (CMU) for the AUTOPLEX Intelligent Base Station system 2000 (IBS 2000) and the Series II cellular telephone systems.
o The completed circuit pack passed all quality inspections and was placed in production.

August 1988 to August 1990:
* Lead Embedded System Developer, Submarine Detection System:
o Designed Non-Acoustic Data Acquisition System (NADAS), consisting of 3 hermetically sealed "bottles" for the US Navy's Surveillance Towed-Array Sensor System (SURTASS).
o System collected data from analog and digital sensors (heading, depth, temperature, etc.) that allowed shipboard computers to "null-out" the shape of hydrophone array and locate enemy subs.
o Completed design placed in production.
o Secret clearance terminated upon end of project

Sept. 1986 to August 1988:
* Embedded System Developer:
o Completed firmware and circuit design for prototype of Intel 8051 based Transmit/Receive Unit (TRU) for the Subscriber Loop Carrier 120 (SLC120) Network Access System's Flexible Access System number 3 (FAS3) project.
o Transferred completed design documentation, hardware and firmware, and prototypes to the systems integration laboratory

Dec. 1985 to Sept. 1986:
* System Engineer:
o Designed architecture for 1.5 MBPS (DS1) multiplexer backhaul interfaces to the AUTOPLEX Hub Cell Site product
o Created cost reduced connection to public switched telephone network (PSTN) by multiplexing multiple 64 KBPS (DS0) digital voice channels from a cell site transceivers through D4 multiplexer bank.

1983 to Dec. 1985:
