Developed interrupt driven software replacement for obsolete FIFO device in voice messaging system; thus eliminated a costly redesign of G3 line card in the fax network node.

Designed and developed a pre-RFC-1613 X.25 over TCP/IP encapsulation protocol using ISODE development tools and a Berkeley socket interface, used between VxWorks based X.25 packet switch and UNIX host.

Designed and developed process internals of fax line card and packet switch platforms based on the VxWorks and MTOS real time operating systems.

Trained 8 Canadian engineers (from CMC successor to NetExpress) in packet switch and fax protocol converter product internals.

Designed protocol for downloading line card executable code and configuration parameters, which represented major change from previous completely ROMed application, thereby saving development time and drastically reducing field upgrade costs. Developed client process for target line cards. Developed server application for UNIX and XENIX hosts.

Maintained fax networking code for continuing releases and bug fixes.

Designed and supervised development of command line user interface to packet switch, for local and remote access. Developed extensions to user interface and to host based parameter and routing table conversion utilities to support second and third generation packet switches.

Responsible for organization and control of the software development environment, including specification and procurement of Sun workstation network. Performed installation and SunOS system administration for a network of 30 workstations and other networked hardware, including packet switches, LAN router, PCs, in circuit emulators.

Developed hardware dependence isolation techniques and libraries for internal data flow in fax line card products.
