EXPERIENCE
Senior System Test Engineer, NextWave Broadband, 2007 - 2009
• Lead System Test engineer for WiMAX device testing. Developed and executed system-level test plans
for smart phones, media players, and modems. Developed and documented standard test procedures.
Developed and maintained GUI-based test automation software (LabWindows and Python), using
base station emulator, spectrum analyzer, power meter, and other automated test equipment.
Assisted hardware and software developers in reproducing problems and verifying fixes. Supervised
two junior engineers.
Staff System Test Engineer, Entropic Communications, 2005 - 2007
• Lead engineer for broadband network testing. Developed and maintained GUI-based test automation
software (LabWindows and Tcl), using Ixia, spectrum analyzers, RF power meters, and other
automated test equipment. Developed and executed system test plans and procedures. Assisted
hardware and software developers in reproducing problems and verifying fixes. Assisted systems
engineers in developing certification tests for MoCA (industry organization).
Software Engineer, Conexant Systems, 2002 – 2005
• Technical Lead for cable modem testing. Developed and maintained GUI-based test automation software
(LabWindows and MSVC using SmartBits, RF sniffers, Ethernet/SNMP utilities, and other
automated test equipment. Maintained problem tracking and configuration management databases.
Performed DOCSIS certification testing and analyzed test results. Assisted modem code developers
in reproducing problems and verifying fixes.
Software Engineer, Ensemble Communications, San Diego, 2000 - 2001
• Wrote hardware diagnostics for broadband wireless base stations (network and modem interface cards
and system controllers), including EEPROM, RAM, flash, digital potentiometers, ATM chips
(ATLAS, APEX), and network interfaces (DS3, E3, OC-3). These diagnostics, running under
VxWorks, formed the backbone of Ensemble's Production Test process. Wrote requirements specs,
user documentation, and interface standards for all diagnostics.
Created GUI-based automated tools for radio engineering and production, including BER determination,
FSK link analysis, radio tuning, and calibration. Built a testbed for automated airlink testing. The
testbed is a GUI-based script engine that controls variable attenuators, power meters, comm interfaces,
and programmable noise generators, using GPIB and LabWindows (CVI) libraries.
Developed a full-featured, GUI-based, terminal emulator for Windows PCs. The emulator, written in
ANSI C using LabWindows, maintains and displays up to 16 communication sessions simultaneously,
and executes interactive command scripts (similar to Tcl/Expect). Supported interfaces include RS-232
(async), Telnet, and Telnet/async (port-server interfaces). The terminal emulator was used by all
Ensemble engineers for base station and CPE testing, and in production.
Lead System Test Engineer, Applied Digital Access, San Diego, 1997 - 2000
• Built a GUI-based test engine based on LabWindows, which maintains full-duplex comm sessions over
async or Telnet connections, while simultaneously executing test scripts. This tool was the principal
test engine for ADA's System Test group.
Wrote scripts to support stress, stability, regression, and feature testing of in-circuit network test systems.
Wrote network element simulators for TL1- and PDS-based cross-connects, and AT&T Local
Controllers. Built library routines for remote control of test instruments and common TL1 functions.
Routines and scripts cut regression test time in half.
Analyzed ADA's marketing requirements, Bellcore documents, and ANSI standards, to derive system test
plans and test procedures, which were essential for ADA's ISO 9001 compliance. Wrote the Installation
and Upgrade Procedures and Software Release Bulletins for end users.
Executed the system test plans for ADA's T3AS/CTS systems, which perform DDS, VF, DS1, and DS3
testing. Tested HCDS, FT1, fault management (diagnostic and real-time fault detection and recovery),
and network element (cross-connect) interoperability. Performed all of ADA's Y2K testing for Bellcore
certification. Tracked problems and tested software modifications. Assisted developers by isolating
problems and writing test drivers and simulators in ANSI C.
Set up and maintained Microsoft Access databases to support System Test work, including requirements,
test cases, test results, and coverage (requirements vs. test cases) matrices.
Consultant, Infocom, Inc. (Internet Service Provider), Richmond, Indiana, 1995 - 1996
• Created test scripts, performed testing and QA on a networked database analysis tool, using Oracle and
Internet protocols (TCP/IP) running on UNIX workstations.
Composed and edited commercial web pages using HTML and UNIX tools.
Taught introductory classes in Internet protocols, browsers, and email.
Senior Engineer, CTA Incorporated, Rockville, Maryland, 1985 - 1994
• Designed and built multi-processor computer systems for acquiring and processing weather satellite data
for NOAA. Integrated VMEbus backplanes, multiple 68xxx CPUs, DSPs, video graphics, Internet
software, real-time operating systems (VRTX and OS-9), boot firmware, C code, and 68xxx and
80x86 assembler code. Developed hardware specifications and drivers for custom analog/digital I/O
boards developed in-house. Served as Chief Engineer, supervising five technical staff members on
successful projects that established CTA as a prime NOAA contractor.
Designed and implemented an SNA-TCP protocol conversion system on IBM Series/1 computers and an
X.25 network. This system was built for IBM, and allowed IBM to bid a major DOD contract.
• Programmed a fiber-optic LAN gateway (FDDI-Ethernet) for NASA, using VMEbus hardware.
EDUCATION
University of Maryland, College Park, Maryland. B.A. in Philosophy, Phi Beta Kappa. . Extensive
science coursework, including organic chemistry (2 semesters), comparative anatomy, statistics, and
biology.
PUBLICATIONS
