and reported any failures to preserve portability and
to support continuous integration among several distributed development teams.
Major projects were
Feith Document Database (FDD)
and Netware for Unix.
FDD is a document imaging system build around MS-Windows clients

of customer problems.
- Wrote platform specific code for Netware for Unix
and fixed deviations found by
a Novell provided series of application, API, and network level
certification test suites.
