Preceding Positions:

Senior Software Engineer, Sterling Software, Moffett Field, CA, November 1996 - May 1998

Coordinated experiments in an air traffic control and pilot simulator laboratory at NASA Ames which involved enhancing and debugging an aircraft flight simulator and the air traffic control simulator, scenario generation, and modifying the flight simulator software to support researcher requirements. Studies supported include the Parallel Approach Logic, Automation Bias and the Advanced Air Transportation Technology (AATT) studies.

Senior Software Engineer, SYRE, Moffett Field, CA, January 1991 - November 1996

Redesigned a pilot simulation program to increase its capabilities by more than 50%. Converted the pilot user interface and radar display from Sunview to XView using X-library graphics routines and converted it from standard C to ANSI C. Designed a histogram and reporting utility. Automated the air traffic control airspace installations. Wrote and maintained the User's Manual for the pilot simulation program.

Senior Programmer Analyst, Duracell Worldwide Technology Center, Needham, MA, January 1988 - January 1991

Designed and procured a 180+ Novell network to replace a Data General minicomputer to increase employee productivity. Managed a Novell network and trained the users in Novell and other DOS programs. Designed databases for data acquisition, employee status and report processing using SIR RDBMS, FORTRAN and Paradox. Designed the user-interface for a battery testing data acquisition system.

Development Engineer, Technical Business Strategies, Ashland, MA, June 1987 - January 1988

Integrated hadware and software components for IBM PC compatibles. Wrote technical manuals for an AI-based Oracle database query language.

Computer Consultant/Teaching Assistant, Simmons College, Boston, MA, September 1983 – June 1987

Instructed students and faculty in the operation of PCs and microVAXs. Supervised a digital electronics and microcomputing lab and led weekly group tutorial.
