My work since 1990 has involved software for communications systems in one form or another: mostly commercial mission-critical carrier-grade products involving all aspects of low to high level design, including architectural guidance and direction, through multiple release cycles, including occasional and necessary on-site troubleshooting and engineering support. Prior to this, and along side of this, I have engaged in various related activities.

"UTS CSE Final Project: The Chocolate Factory" (UTS, June 1995)

For my final undergraduate team project, I had shared responsibility (with 2) for architecture definition (systems, protocols, scenarios), and project management for a team of 15: established development processes and documentation, including revision control; developed a communications API and system-test emulators for use by development teams; and generally assisted in development activity, code reviews, design and development, testing and integration, and technical direction.

"UTS CSE Final Thesis: Congestion Control in Wide-Area TCP Networks using BONeS" (UTS, November 1995)

For my final undergraduate thesis, I developed a minimal (but functional) TCP implementation; a BONeS framework of building blocks for modelling wide area networks; and simulations to investigate TCP congestion control scalability issues -- resulting in (a) initial thesis report: project investigation/feasibility; (b) final thesis report: detailed information of activity; (c) final thesis presentation: overview, conclusions and directions.

"Development for a commercial ISDN PC-card product" (Jtec, January 1996)

For a commercial ISDN PC-card product, I developed a proprietary SLIP protocol to interconnect RTOS systems, mechanisms to spoof IPX packets and LAN bridging, proprietary NMS extension (GUI + embedded), various maintenance, installation activities.

"Development of next-generation multi-product telecommunications software architecture" (Jtec, January 1997)

For a commercial telecommunications product, I developed a next-generation multi-product software architecture using C++, Rose, as technical lead, for processing heterogenous data sources, with dynamic and configurable embedded components, including requirements, high level design, low level interfaces, application notes, an implementation of the IETF RFC-908 RDP protocol, generic embedded task software components, testing and emulation stubs, a set of enterprise SNMP mibs with corresponding embedded C++ object wrappers around C based SNMP agent, serial data processing tasks, plus adapters and test loopback components, a build environment, coding standards, etc.
