Summary

 

 

I have been awarded three software patents based on my system architectures. Over the past 20 years I have continuously led technical teams for various hardware and software product lines; many of the products were award-winning and continue to generate revenues for investors. I have built and led technical teams of three to twelve engineers, inspiring team members to innovate, collaborate, and build products for market.

My accumulated senior level engineering expertise involves designing hardware and software at all logical levels, transistors to complete processors, machine code to Smalltalk, and embedded RTOS kernels to graphical applications, primarily in the domain of Data Communications.

Businesses best served by my skill set require an experienced technical team leader with extensive scientific and leadership background, to direct and inspire engineering workgroups to innovate and develop new technologies for market.

Experience

 



Co-founder and Chief Scientist

 

2001-2006

Singlestep Technologies Corp , Seattle WA

 

á Primary responsibilities include creation, architecture, design and development of corporate core technology, the VNOS platform. VNOS is a graphical data-flow based rapid prototyping and deployment environment and engine. It runs on Windows 2000+ and Mac OS X with visual interface, and on Linux as a server daemon.

á Added features to VNOS, including lazy graphical updating, in-memory Perl scripting, and VNOS expression macros.

á Technical lead and prime mentor of the Engineering Department.

á General technology resource to other groups.




Independent Consultant

 

1997-2000

Warman Consulting, Seattle WA

 

Client work included:
á Legacy IBM SNA printer stream to Xerox printers, using embedded 80188 hardware for protocol conversion and printer driver/translator running under Linux.

á Architected and designed Data Transfer Bus, Audio isochronous channel engine, Sample de-jitter digital PLL, and ARM interfaces between ARM in an ASIC and the media engines in a Xilinx Vertex FPGA.

á Acted as technical due-diligence investigator for several companies.

á Continued development of VNOS: implemented Forth (initially for debug), data flow connections, virtual widgets, widget building wizard, property editor, and the basic set of virtual.


 




Co-founder and Chief Scientist

 

1989-1997

Lone Wolf Technologies, Redondo Beach, CA and Seattle, WA

 

á Co-invented the MediaLink Protocol

á Designed and implemented the RTOS and channeling firmware for the Motorola-based 68HC11 MidiTap MIDI network product.

á Architected, designed, and implemented Visual Studio, a management tool for the MidiTap network.

á Architected and implemented the lower speed ML125K asynchronous version of the MediaLink protocol engine, which retargeted the technology as an OEM device management for networking Professional Audio equipment

á Re-targeted the Visual Studio code to support the ML125K networking. This software was the first called VNOS (Visual Network Operating System

á Was an active participant in the Midi ManufacturersÕ Association (MMA). Contributed materially to the Show Control Protocol.

á Was an active participant in the AES Working Group 10, later the SC-10 Standards Committee.

á Company renamed to MediaLink Technologies Corp. in 1994.

á Designed and implemented a MediaLink FPGA (Xilinx 4025) that conveyed CD quality audio streams autonomously and isochronously, using the 68HC11 as a stream manager.

á Designed a DMA MediaLink controller in Xilinx 4025 this time driven in-band by an i960 processor. Handled multiple voice quality channels.
