Work Experience

2002 - present Senior Systems Analyst, Lockheed Martin Management Systems Designers, Inc., Fairfax, Virginia

National Center for Biotechnology Information (NCBI), National Institutes of Health (NIH), Bestheda, MD

Supporting the Gene Expression Omnibus (GEO) database project. GEO is a gene expression and hybridization array data repository built to support the public use and dissemination of gene expression data. Development support is being provided for the submitting, retrieving, and analyzing of gene expression data through Web-based applications.

2001 - 2002 Contractor, Maxim Group, (now TEKsystems, Inc.) Rockville, Maryland

NCR, Rockville, MD

Developed C++ code in a Visual C++ environment on Windows NT for the USPS PosOne retail system. The code extensively uses MFC and COM. Designed and developed a tool to produce and maintain a graphical representation of the system's workflow to aid developers in maintaining the workflows.

1997 - 2001 Senior Consultant, Emerging Technologies Consultants, Inc. (Braun Consulting, Inc.), Reston, Virginia

Total Commisssions Solutions

Worked on the design and implementation of Total Commission Solutions. The design and implementation work included the data base schema, database scripts, the core calculation engine, and the user interface. Tested and debugged the current 3.0 version of commissioning as well as working on the design for the Clarify ClearSales Commissions product. Implemented specific commissioning applications for Clarify customers.

Teligent, Inc., Reston, VA

Worked on the design and implementation of a commission tracking system (CTS). The project core was written in C++ and utilized COM/DCOM (through ATL) and OLE DB to connect the core engine to the GUI and the database. The GUI front end utilized Visual Basic.

MCI, McLean, VA

Worked on the design and implementation of a workflow manager. Introduced Petri Nets as a notation for expressing the workflows. Also designed a simplied, easy to use, graphical language for describing the workflows The project used C++ with STL, Corba, OLE, Windows NT, and Unix.

1995 - 1997 Software Engineer, The Dalmatian Group, Inc., Millersville, Maryland

MCI, McLean, VA

Worked on the design and implementation of a workflow manager for MCImetro, McLean, Virginia. Introduced Petri Nets as a notation for expressing the workflows. Also designed a simplied, easy to use, graphical language for describing the workflows The project used C++ with STL, Corba, OLE, Windows NT, and Unix.

Lockheed Martin, Rockville, MD

Analyzed the performance of the user interface of the NERC air traffic control system. The project uses TeleUSE, C and Ada.

Network Programs, Piscataway, NJ

Implemented screens for a telecommunications customer application using TeleUSE and C++.

1995 Senior Principal Analyst, MicroTemps, Reston, Virginia

Computer Sciences Corporation, Falls Church, VA

Designed and built a set of reusable Motif user interface components. Each component was built as a C++ class in a C++ framework. Used the UI components to implement user interface screens for a troop and supply movement simulator for the US Army.

1994 - 1995 Independent Consultant

• Provided GUI programming and consulting for EVB Software Engineering, Frederick, MD.
• Ported a C++ graphical user interface toolkit from Unix to OS/2 and Windows/NT. Prototyped a directed graph editor using the toolkit for The Dalmatian Group, Inc, Reno, NV.

1986 - 1993 Graduate Student Researcher, Department of Information and Computer Science, University of California, Irvine.

Worked on the design, implementation and testing of two UIMSs. Was the primary designer of the second, a client-server UIMS.

1985-1986 Teaching Assistant, Department of Information and Computer Science, University of California, Irvine

Taught introductory assembly language labs and assisted with a compiler theory course. Created lectures, assignments, quizzes and tests for the courses.

1984 - 1985 Student Consultant, Computer Center, Indiana University, South Bend

Helped students use the available computer systems to do their assignments and, was the computer operator during the weekends.

1984 - 1985 Computer Science Tutor, Department of Mathematics and Computer Science, Indiana University, South Bend

Tutored students having problems with their computer science class assignments.

1981 - 1982 Teaching Assistant, Department of Physics and Astronomy, The University of Iowa, Iowa City
