DNA built a platform to accelerate social game development and iterative improvement. Along with a complete social game engine, this included a system that allowed for any feature/hypothesis to be deployed to a subset of real users and analyzed against key success indicators like engagement, retention, virality and monetization. In 1 year we built the platform and 3 successful games on top of it.● Developed technical vision and plan to close A-round funding and kick-off development● Worked with executive team to build, develop and manage lean, high-caliber team● Drove technical design, planning, implementation of core platform including●● Low latency, linearly scalable, write-intensive, game cluster●● Built framework for feature testing and machinery to provide continuous analytics●● Automated build, test and release pipeline● Drove dev of automated, zero-downtime deployment and health monitoring systems● Managed 24x7 operations with 4.5 9's uptime● Drove technical due diligence to close acquisition by Zynga

Doppelganger developed vSide, a stylish, music and fashion oriented, 3D virtual world. It provided an rich, immersive social experience where avatars live and socialize in hip cities with all the trappings - cool apartments, fashion, clubs, music and dancing all controlled by the users.● Joined as founding CTO to build team and bring initial vision to life● Drove the architecture and implementation for game that supports large crowds, incremental, fast loading of continually growing asset library (e.g., environments, avatars, animations, clothing, furniture, etc), embedded music and video, mini-games, in game commerce and and user controlled spaces. ● Built, managed and guided a talented 17 person engineering team with the wide array of skills required to develop a Massively Multiplayer 3D Game ● Championed and guided an agile design and development process that involved product management, art, engineering and community. This approach was unusual in the 3D game world and allowed us deliver complex, iterative, measurable improvements on a weekly basis.● Individual coding contributions included: ●● Script-driven client simulation framework to support massive load testing ●● Elastic instancing system to support user controlled spaces in the world ●● Continuous integration system across art and code ● Facilitated sale of Doppelganger to Hip Digital in December 2008 and went along to drive execution of user acquisition strategy and aid in additional fund raising

Guided planning, design and development of WebLogic Server versions 8.1 and 9.0. Worked closely with product managers, development teams and QA teams spread across five sites. In addition to general technical oversight:● Drove the revamping of the product design and development process to employ more comprehensive customer input and join product management and engineering at the hip. This enabled the delivery of some of the most ambitious and well-coordinated releases in the product's history.● Drove major improvements to product quality and performance (employing scenario testing, stress testing and global performance tuning) leading to release 8.1 which was the highest quality release in product history.● Drove the WebLogic 9.0 release, which was our most ambitious releases to date both in terms of technical sophistication and in terms of integration. It's highlights included substantial improvements to operations, administration and management (including support live application updates without service Interruption, automatic server tuning, and a centralized configuration and monitoring system), a major upgrade in enterprise messaging capabilities and performance, and a major JEE spec upgrade to 1.4.

Member and later lead of WebLogic core team. Contributions included:● Designed and developed the core cluster infrastructure which provides the underpinning for WebLogic's high availability and linear scalability● Provided architectural and coding support to all teams to aid building reliable, scalable and fault tolerant software● Played instrumental role in the constructive evolution of the WebLogic team from a small start-up to the core of a billion dollar/year business

Member of team developing consumer-oriented video editing system allowing novices to construct movies using state-of-the-art editing techniques

Principal member of team investigating Java’s potential as a high-performance server runtime● Ported Java to Tandem’s fault tolerant Nonstop Kernel operating system. This became the foundation of Tandem's production JVM.● Led team developing the reference implementation for the original Java Transaction Service specification.

Worked with team of electrical and software engineers to specify, design and implement a Windows based tool for debugging Field Programmable Gate Array designs in circuit. Contributions included:● Designed core FPGA simulation model● Lead UI design and development effort● Developed developer-friendly regression testing framework and worked with team to implement a continuous testing practice
