May 2004
   Currently tutoring University of Maryland students in Java, C/C++

May 2003
   Acquired C (92%) and C++ (88%) certification through
www.qwizonline.com. (See my website for test results )

Jan 2001 to Nov 2001
    On hiatus to study object oriented software development at home,
including C++ (STL), Java, and UML. Obtained Sun Java 2 Programmer
Certification. (Java 2/Swing and C++ software samples available on my website. )

Sep 2000 to Dec 2000
Software Developer
Darwin Partners Consultant for Andersen Consulting at Marriott Corp.
Gaithersburg, Md.
   Supervised team of software developers during initial production
period for a new Marriott billing system. Software processed billing
transactions using C, Pro C  and CMVC on IBM-AIX. Also developed SQR
report scripts and created document suggesting improvements, including
unit test plan design, better requirements, API library creation, and
suggestions to increase software efficiency.

April 2000 to August 2000
Software Developer
Darwin Partners Consultant for TRW at
Goddard Space Flight Center, Greenbelt, Md.
   Developed satellite data processing software for the NASA EDOS
project using C, Oracle, TCP-IP, UDP-IP and Motif on HP-UX. Work
included Motif user interface modification, replacement of Oracle
queries with UDP-IP for greater efficiency, and implementation of
TCP-IP command andcontrol mechanism.

Sep 1997 to April 2000
Senior Programmer Analyst
General Sciences Corporation/SAIC 6100 Chevy Chase Drive Laurel, Md.
   Developed software for the NASA MODIS project, including
C/Motif/Sybase maintenance and enhancement of SEAWIFS data processing
software; C/Motif logfile viewer; Perl/Sybase/FTP data ingest/export
subsystem, ported to C/Motif/Sybase; Perl/Unix shell script
utility/database management scripts; C/Motif/Open GL data visualization;
RCS based configuration management software for source code management
and software releases; Redesign of core processing software to improve
efficiency and error handling.

Jan 1995 to Sep 1997
Systems Software Engineer
Cambridge Research Associates 1430 Spring Hill Road, Maclean, Va.
   Developed graphics and user interface software for PowerScene, a
three dimensional perspective scene generator that runs on Silicon
Graphics workstations. Work included a C/Motif/Sybase user interface
displaying route and annotation overlays, Perl/Unix shell script
utility/database management scripts, and design and development of
PowerScene PlanView, a C/Open GL/TCP-IP/Xlib two dimensional scene
viewer. PlanView displays ADRG map and remote sensing image data and
allows user panning, magnification, map scale and image resolution
selection and route, annotation, and line overlay displays. Developed
PlanView PC prototype, and ported PlanView to VxWorks.

Apr 1993 to Mar 1994
Applications Programmer
Research and Data Systems Corporation 7855 Walker Drive, Greenbelt, Md.
   Developed C/IDL/Motif graphics and image processing software for a
NOAA Advanced Very High Resolution (AVHRR) Global Vegetation Index data
processing project. Software corrected sensor drift, implemented a cloud
screening algorithm, displayed image data and created color palettes,
and allowed time series display and image subset extraction.

Jan 1988 to Mar 1993
Senior Programmer Analyst
Hughes STX Corporation 4400 Forbes Boulevard, Lanham, Md.
   Developed software for the Small Expendable Deployed System (SEDS)
Delta rocket launch which studied tethered satellite capabilities.
Responsibilities included C telemetry data processing software and a
C/Iris GL 2-D graphical simulation of a tethered satellite.
   Supported the Laboratory for Terrestrial Physics scientific research
community through user training and consultation, and graphics and image
processing software development:
LAS (Land Analysis System) and EASI/PACE image processing software
development; C/IRIS GL software that plotted irregularly spaced
geochemical data points as surfaces; C/IRIS GL/Motif map visualization
software that plotted a color coded map database on the Earth's surface.
Options allowed multiple color coding algorithms, annotation,
interactive magnification and panning; C/IDL software that plotted
geomorphic structures and compute statistical probabilities; C
reprojection and subsampling software of Mars sinusoidal topographic
imagery.
