Aehr Test Systems, Mountain View, CA
November 1996 - August 1997

° Debugged and enhanced real time Borland Turbo C code running in MS-DOS for integrated circuit Pick-and-Place machine. Incorporated new software features supporting new hardware enhancements

Westinghouse Security Electronics, Santa Clara, CA
August - October 1996

° Real time keypad support added to keyless entry system firmware. PL/M development in MS-DOS /
Windows 3.11 for both standalone and proprietary-networked operation.

Fujitsu America, Inc., San Jose, CA
September - November 1992

° Enhanced and debugged MS Windows, C++ fiber-optic telephone system control application. Removed recalcitrant memory leaks, developed graphic window scrolling and enhanced hidden graphic object repaint performance.

Radiant Systems, Inc., Lenexa, KS
February and May - June 1991

° Developed simulation of Nurse's Station medical instrument network monitor using Smalltalk in 80386 environment. Client enhancements to Digitalk Smalltalk V/286 provided additional objects useful for the simulation. Considerable Smalltalk logic coding was required to adequately perform the simulation.
