Overview & Objectives
I have a track record in systems engineering and solutions delivery that spans more than
twenty years. My experience has comprised successful startups to multinationals and
encompassed wireless, military, data, and multimedia communications. A proven problem
solver, I work with stakeholders across both external and internal organizations to find
solutions that align business goals, technical capabilities, and customer needs. With
thorough experience balancing the demands of concurrent projects in different phases, I
have continuously fostered successful outcomes under varying constraints of organization,
schedule, and resources.
My goal is to help companies innovate. I work with companies that are developing products
and systems that help people communicate and interact with information, more efficiently,
and in new and novel ways.
I provide contracting/consulting services to companies in the following areas:
product engineering
product management
innovation
architecture & standards
Skills and Expertise
Through the responsibilities that I have had, and the people with whom I have worked, I
have developed a breadth of skills and expertise that includes:
leadership and vision: I have successfully championed product and standards directions,
led the introduction of new technologies into companies, and redefined the business
direction for a startup company.
proven innovator: for every company I have worked with I have a track record of
innovations solving previously intractable problems and/or fostering new products and
industry solutions.
excellent communicator: I have written and presented proposals to customers world wide,
responded to RFPs and RFIs, spearheaded industry standards efforts, created and presented
courses, and written countless engineering specifications.
strong interpersonal skills: With over ten years experience in a systems engineering role
with little explicit authority, I have continuously fostered successful outcomes by
negotiating and mediating solutions between different groups and departments,
organizational levels, and companies.
sound judgement: I have specified product architectures that have been successfully
developed, managed product requirements definition and capture for market leading
products, balanced short term requirements against longer term strategic goals, and
provided technical guidance throughout development phases.
quick study: I have consistently taken on challenges in complex areas such as multimedia
over IP and cellular data communications, mastered the necessary knowledge and skills, and
applied those to create successful products, protocols, and business solutions.
Work History
IETF Media Control Work Group2001Present
The Internet Engineering Task Force (IETF) is the standards group responsible for
developing Internet standards. It is an open organization where anyone with the
willingness and ability can contribute to the evolution of the standards that govern how
the Internet works. I became involved with Media Control standardization while at Convedia
and since then have been a principal architect of that effort.
co-designer of the architectural solution used for media server control and co-author of
the standards specification for the Media Control Framework (RFC6230).
led the original design teams tasked with finding Work Group consensus directions for
Interactive Voice Response (IVR) and mixer control solutions.
co-author of the standards specifications for IVR Control (RFC6231) and Mixer Control
(RFC6505).
key author and editor of the informational document that provides an overview of the
media server control framework (RFC5567).
System Architect, Convedia Corporation; Vancouver, BC 20002005
Convedia was a startup company when I joined in 2000. During my tenure, the engineering
team grew from about forty people to close to one hundred individuals. The company was
sold in 2006 for over 100M USD, returning a significant profit to its investors. Reporting
to the VP Engineering, I was a key member of the engineering management team that led the
creation of Convedia s market leading media servers. My key contributions included:
created the MSML protocol and defused a threat posed by a competitor s standardization
effort. MSML became the companies key control protocol, was implemented by several
competitors, and influenced current IETF standardization.
worked directly with major customers and partners such as AT&T, Huawei, Siemens, and
Ericsson, to create formal feature specifications that drove the engineering requirements.
These specifications formed the basis of Convedia s commitment to those customers and
partners.
led the requirements definition process. This involved negotiating with and mediating
between engineering teams, and business development, product management, and marketing
leaders, to create and manage the top level Engineering Requirements Specifications. The
specifications ensured that all groups within the company had a timely, accurate snapshot
of what was in each release. They allowed reliable releases to be delivered on time, and,
when market or business conditions changed and tradeoffs became necessary, contributed to
better decision making.
specified the external product interfaces and consistently insured that they were both
the most standards compliant and the most comprehensive within the VoIP enhanced services
market. These interfaces used SIP (and extension standards), SDP, RTP, VoiceXML, MGCP, and
H.248.
trained customers and partners in the use of Convedia s control protocols.
represented Convedia within the Internet Engineering Task Force (IETF) and the Voice
Browser Work Group of the World Wide Web Consortium (W3C).
Chief Architect, inClarity.com; Vancouver, BC 19992000
inClarity was a start-up company developing Web-based directory services and technologies
for consumer oriented vertical market segments. I was one of the original four people who
initiated the concepts and shared responsibilities for most aspects of creating the
business. The activities in which I directly participated included market research,
concept development, competitive analysis, business plan, and strategic partnerships.
Principal Staff Engineer Architecture and System Design Group, Motorola Wireless Data
Group; Vancouver, BC 1994 1999
created the architecture for a circuit-switched Inter-Working Function for CDMA 2.5G
networks. Presented the architecture to Motorola s Cellular Infrastructure Group and won
their business. Following development, Motorola was able to commercially offer the
function before its major competitors.
wrote and presented technical proposals to the Motorola Cellular Infrastructure Group,
and/or to their customers, major carriers within North America and Japan. The proposals
covered CDMA circuit/packet switched products, wireless ISP integration and consulting,
and a mobility testbed.
managed the technical proposal responses to major European carriers requesting proposals
for Motorola s GPRS support nodes and affiliated IP/VPN infrastructure.
within tight engineering and schedule constraints, I spearheaded the development and
adoption of a distributed deployment architecture for Motorola s CDPD system. This
addressed market scalability and availability requirements and led our initial flagship
customer to award Motorola the system rollout contract.
