Technology Summary

Professional Experience

At NGS Solutions I provide system engineering, system/software architecture and software design/development services for client companies developing a variety of communications and embedded products. Clients range from large networking and communications companies such as Bay Networks, Nortel Networks to early phase startups such as Fleet Technology and Stream Market Research. Projects range from system engineering and architecture development, OS and communications stack development, user-interface design and implementation to writing device drivers for proprietary devices. Projects were performed using a variety of different processors from Cypress PSOC, Intel x86, and Motorola 6805, Coldfire, 860, 8260. The operating systems range from BSD/Linux to PSOS and VxWorks. Smaller projects, such as the 6805 require the creation of simple round-robin executive. Languages used range from Assembly, C, C++, Qt (GUI builder), Java/Javascript and HTML.

In the 14 years prior to NSG Solutions, I’ve held various consulting positions as a Software Development Consultant for companies and organizations such as Lincoln Laboratories, Concurrent Computers, Xylogics, UB Networks, Newbridge Networks, Bay Networks and Nortel Networks. Additionally, I’ve also been employed direct as a software engineer and architect at such companies as Packet Technology/River Delta, WinData, Raytheon, BioRad, Marshall’s, and Sears.

Notable projects:

• Created network services package, networking daemon and BSD socket interface for eRTOS/Waterloo TCP/IP stack. This provides the standard BSD network services and API in the same fashion as today’s BSD/Unix systems. Which allows easy ports of common applications into the eRTOS/Waterloo environment.
• Ported the NetBSD networking layer to run under VxWorks, one MPC8260 as the core of a high performance software-based packet engine for audio/video/voice over IP. Designed and implemented the core software to perform the packet-switching, rate-limiting and queuing disciplines for the software-based packet engine. This software core was written in C++ and prototyped and tested on NetBSD.
• Created the architecture and developed software for an audio/video streaming product for the Harris Intralink-IP product. Product was based on a MPC860 platform running VxWorks. Also developed a suite of tools running on Linux/BSD to provide a test environment for Intralink IP.
• Design and development of NAT routing software based on the BSD IP Filter package for UE6XX product line of Sonoma Systems/Nortel Networks. Also created a test environment to run this NAT implementation on FreeBSD and Linux. This allowed testing and debugging to occur in a user-friendly environment, than afforded on the embedded platform.
• Rewriting Telogy Golden Gateway software to enhance performance, writing an ATM SAR, and adding ITU 363 call processing capabilities to handle modems for a voice card for the UE6xx product.
• Designed and develop a suite of Java based tools to spider websites, cache web content, manage web content and share content with other users. This was for an early phase startup, Stream Market Research.
• Designed and developed remote car starter software that implemented a unique user interface to allow programming by the installer to enable selected features for the customer and could also learn the button codes for most companies remotes to eliminate having multiple remotes. This was based on a Motorola 6805 and written in C and assembly language.
• Designed and developed a prototype for the ITWS weather RADAR display system for Lincoln Labs. I developed weather product display and communications classes using C++ and OpenGL on SGI/Sun workstations. The weather product communications classes allowed nodes in the ITWS system to discover and display new weather products dynamically.
• Designed and developed a prototype for a user-tunable digital electronic motorcycle ignition system. This allows dynamic tuning of the torque and power curves for the antique motorcycles. This is based on an automotive quality 6805 and written in C and assembly.
