I provide technical consulting advice on WebRTC for the team at Caffeine on an as-needed basis.

I was recruited by Mozilla in late 2012 to help with Firefox's implementation of WebRTC, including design, implementation, and unit testing of associated code. During this process, I worked with others to standardize protocols for voice and video communications in web browsers in the IETF RTCWEB and W3C WebRTC working groups, in many cases driving forward difficult and controversial decisions by finding novel compromises that the involved parties found acceptable.In April of 2014, with the underlying WebRTC platform becoming more stable, I led the creation of a WebRTC-based browser feature, called Firefox Hello, as its technical architect. Firefox Hello enabled real-time communications directly from inside Firefox. I created the network-level architecture and software architecture for Firefox Hello, prototyped select aspects of the feature, and worked with a team of 12 engineers to implement and deploy the service to 350 million users.In late 2015, I worked with the senior engineering director for the Firefox product to provide an architectural review of key Firefox features. I also represented Mozilla in the W3C WebPayments working group to ensure that the next-generation payments platform that will be deployed on the Web enables an open and fair ecosystem for existing payment providers -- both large and small -- as well as new companies that may emerge in the future.

• Principal Engineer, Office of the CTO: In this role, I was a member of an eight-member team selected by the CTO to provide strategic input to Tekelec’s product direction. I interfaced with key customer accounts to probe for future needs. I was responsible for identification and refinement of opportunities to prototype future-leaning technologies. I formed strategies regarding standards body participation, as well as performing such participation as necessary.• System Architect/Product Architect: I creared network and product architectures for a SIP to SMS gateway and an IP load distribution product based on general purpose hardware running a modified Linux distribution. I was responsible for all aspects of system behavior, including performance, scaling, and reliability.• System Architect/Customer Liaison: In developing AAA server for a major US wireless carrier, I liaised between the customer’s planning and operations organizations and Tekelec’s engineering and product management organizations. I worked closely with the customer to gather requirements, and convey questions and concerns from the engineering team. I designed the system architecture for the product, including network scaling, redundancy, partitioning, and availability mechanisms.• Sales and Marketing Support: I joined Tekelec’s sales teams on frequent customer visits to act as a sales engineer on our new and emerging real time technologies. I spoke regularly at Tekelec’s “Experts Forum” customer events, as guest speaker for Tekelec’s Webinar series, and led a variety of customer training courses.

Bootstrapped start-up working in real-time communications software as a managing partner. Governed contract reviews and customer relations, guiding architecture design for SIP presence and SIP proxy system based on reSIProcate codebase. - Invented system for granting high-density cellular access over standard IP networks, prototyping method of interoperating SIP/IMS networks directly with cellular eNodeB “Interoperability Specification” (IOS) interface, suitable for embedding in cellular femtocells.- Designed, implemented, and licensed OpenSigComp library, building and testing open-source implementation of RFC 3320 “Signaling Compression” used to reduce signaling message size on radio links, generating revenue used for future product development.Implemented Call Center Quality Monitoring: High-volume component to transform traditional telephony into VoIP-software-compatible system.- Elevated quality monitoring practices, expanding legacy systems working with circuit-switched PBXes to variety of packet-switeched VoIP systems, including from Cisco, Alcatel, and Nortel.- Spearheaded entire product development lifecycle (PDLC), building network architecture from scratch, creating pitch decks to reassure potential clients, reviewing and negotiating contracts, and harmonizing creative efforts across team.- Reverse-engineered three different vendors’ proprietary protocols, documenting entire process.

I served many roles in this position, including system architect, solutions architect, product architect, component designer, component developer, researcher, external consultant, and partner interface for a variety of systems, including wireless presence and cellular walkie-talkie systems.
