Suddenly Social, Inc., Palo Alto, California
2010-2012: Chief Technology Officer & co-founder
Main founder and CTO of a startup aimed at the mobile online games market, founded by a group of Lucasfilm Games alumni. Our goal was to create game experiences that used mobile devices to overlay online game worlds with the real world in which players were physically present, using, for example, a smart phone's GPS receiver, accelerometers, and gyroscopes to correlate the player's physical position and actions with corresponding behavior in the game environment.
In support of this, I created a highly scalable server platform that enabled large numbers of mobile device and web browser-based clients to stay continuously connected in real time (a single instance of this server running on an AWS "large" virtual machine could support 150,000 to 200,000 concurrent users sharing a common game experience, and could scale to as many servers as needed to accomodate the load). Licenses and support contracts for this technology became the company's largest revenue source.
Responsible for all technical activity at the company, including supervising the engineering staff and contractors. Also heavily involved in technology license negotiations, technical sales, and fund raising (the latter included both obtaining initial venture capital investements and negotiations involving acquisition by another company).
MSB Associates, San Mateo, California
Member of a small team of elite, highly experienced technology professionals consulting in the areas of software engineering, computer security, social media, online games, patents & other intellectual property, product design & product management, and business strategy.
As a consultant, notable clients have included Zynga and Microsoft, as well as numerous law firms. Projects have included developing online fraud prevention and abuse mitigation technology, assisting clients with software reengineering and legacy code issues, and working on advanced operating system concepts. Legal work has focused on assisting clients with expanding patent portfolios and functioning as a technical expert for the defense in patent litigation, especially locating and documenting patent-invalidating prior art.
WeMade Entertainment, USA, Kirkland, Washington
2008-2009: Chief Technology Officer
Responsible for fundamental technology, platform architecture, and overall engineering management for the newly formed North American wing of established Korean online games developer and operator WeMade Entertainment. WeMade USA's mission was focused on providing the parent company with an organic western cultural competency in the online games business, rather than simply localizing existing Korean properties. This included strategic acquisitions in the west as well as direct production of western-sourced game content. Though WeMade is a large company, the US organization functioned as an autonomous startup.
In addition to setting up and managing the company's engineering organization as a whole, my work concentrated on development of a gamer-oriented community service targeted at players of the company's games. This service was differentiated from many of the other entrants in the crowded social networking arena in its enthusiastic embrace of the mix of both real and fictitious personae that characterize MMOs, and in its robust support for the fundamentally tribal nature of many gamer groups, in contrast to the more lightweight, interest-centered group abstractions characteristic of many competing services. I was in responsible for primary product design for this service, in addition to the technical aspects.
Yahoo!, Sunnyvale, California
2005-2008: Principal Technical Yahoo, Communities & Identity
Principal architect and development team leader for the Yahoo! Core Identity Platform (CoreID). CoreID provides a unified framework for the storage, retrieval and presentation of identity information for all of Yahoo!'s 500+ million registered users. The platform consists of a set of webservices available to all of Yahoo!'s many disparate properties, along with client software, user interface components, user interface design standards, and a set of best practices for the handling of this information throughout the Yahoo! network. The platform is currently deployed in some half-dozen data centers around the world, and most Yahoo! properties are now integrated with it.
Principal architect and development team leader for the Yahoo! Reputation Platform, a general purpose system for the collection, management, and analysis of reputation information, exploiting the knowledge extractable from the emergent patterns of behavior of large populations of users. The platform is implemented as a highly scalable dataflow engine, passing fragments of observational data and user input through graphs of simple agents. These graphs then implement various models of reputation and revealed preference.
Member of Yahoo!'s Social Media advisory group, a small team of senior executives and trusted experts chartered with identifying key thinkers and influencers in the online communities and social media space and bringing them into Yahoo!'s orbit as employees or advisors; with focusing research and development initiatives in this area; and plotting overall corporate strategy for leveraging the unique asset that is Yahoo!'s enormous registered user base.
Avistar Communications, Redwood City, California
Principal architect refactoring a large codebase (~1.2 million lines of C++) for a high-end desktop video conferencing and telecommunications system, in service of a strategic corporate transition from being primarily a hardware company to primarily a software company. Although the system in question is highly capable, it was not originally constructed with an eye to modularity or portability, since the primary platform was initially the company's own proprietary hardware product. The ultimate goal of this effort was to remodularize the software so that components may be licensed to third party hardware manufacturers in the form of a "Video Operating System".
Reengineering efforts centered on imposition of rigorous coding standards, removal of large amounts of excess mechanism and spurious complexity, and bottom-up refactoring of major abstraction boundaries that had grown tangled and murky over the product's 10 year history. A big piece of this was coaching and mentoring the existing software development team (10-12 engineers) to help them improve their design skills, engineering intuition, and code quality.
A significant initial achievement was the incorporation of video-over-IP technology into the product's video call routing and management infrastructure, which historically was based on circuit-switched analog video. The product's original circuit-switched connection abstractions proved an ideal substrate for building a general-purpose resource management framework for bandwidth, even over packet-switched networks. The IP-enabled version of this system was released to customers in summer 2004.
State Software, San Jose, California
2001-2002: Chief Architect and Board Member
Architect and principal server developer for the State Application Framework, a platform for delivering stateful, real-time, interactive, single- and multi-user applications over the web. This product enabled customers to develop applications possessing the responsiveness and interactivity conventionally associated with installed desktop application software, yet it allowed these applications to be presented to end users within the users' own standard web browsers. This was an early manifestation of the approach now commonly referred to as Ajax, allowing the application to be delivered directly in the browser without recourse to plugins, Java applets, downloads, software installations or other like barriers to adoption and use. Customers included A.T.Kearney (a division of EDS) and Amazon.com.
Developed techniques for running a virtual full-duplex, object-to-object message channel over standard HTTP, avoiding the interference of firewalls and proxies while delivering excellent real-time client-server interactivity. This sort of technology is nowadays sometimes referred to as Comet. Developed a highly scalable server architecture which can support thousands of concurrent user sessions on a mid-range server machine and, potentially, hundreds of thousands to millions of concurrent users in a modest server farm.
Communities.com (formerly Electric Communities), Cupertino, California
1995-2001: Chief Scientist and Board Member
Lead architect of communications protocols and object technologies to facilitate effective commercial and social interaction over computer networks. Developed advanced infrastructure technology for a highly secure, distributed, extensible object system to support commerce and virtual world applications. (As the result of a shift in company business strategy, important parts of this technology were released as open source software, principally in the form of the secure distributed capability programming language E. See http://www.erights.org.)
Undertook engineering overhaul of acquired technologies, including the leading Internet graphical chat system (The Palace), significantly improving product flexibility and reliability (for example, increasing server MTBF from a few hours to several months). Produced second generation server as part of a small team which significantly upgraded the company's technology, yielding significant technology licensing revenues even while CEO was bankrupting company trying to create a media portal.
