The Social Web Foundation works to grow the social web aka the Fediverse in an open, healthy, and sustainable way--working with technologists and the public to build a new global town square that works for everyone."

Co-organizing FediForum, the unconference for the people who move decentralized social networking and the Fediverse forward. https://fediforum.org/

Developing UBOS, an open-source, multi-platform Linux distribution for personal servers and Indie IoT devices; UBOSbox Nextcloud, a ready-to-use, fully managed home server for private file management, calendar sharing and others, in the privacy of your home.

Bringing the conversation of ethics, privacy and personal data into the heart of Silicon Valley. http://mydatasv.org/

Coding/data science competition In partnership with Facebook Data for Good, the Delphi Group at Carnegie Mellon University (CMU), the Joint Program on Survey Methodology at the University of Maryland (UMD), the Duke Margolis Center for Health Policy, Resolve to Save Lives and Catalyst @Health 2.0. I'm one of the judges.

Member of the board of directors of this new not-for-profit.

Transitioned into a technology/product advisory role from my previous role as system architect.

Brought in to help Lunera to transition from hardware-only “dumb” LED lighting products to a recurring-revenue IoT software platform company. As the most senior systems architect on the team, I lead the design and implementation of all aspects of the system, including: the IoT software platform in the cloud, all firmware, communications, big data, machine learning, their integration and quality assurance. Introduced engineering processes and selected most tools. Recruited, supervised and mentored embedded and cloud developers, quality assurance, and devops; supervising off-shore application development team. Vendor selection. Wrote first version of the embedded C++ firmware, and various components in Java, Python, PHP and Perl. ALso helped them recruit a CTO from Google.

Informal monthly get-together for people building Personal Clouds and everything that relates. See http://personal-clouds.org/

Among others: Developed and marketed Java NoSQL graph database, InfoGrid. Conceived and implemented first decentralized, URL/PGP-based digital identity system for the internet. Developed, deployed and supported a mobile, real-time health records web / messaging application with asynchronous enterprise integration for emergency room physicians. Performed various enterprise architecture, systems design and technology advisory projects for enterprise customers in healthcare, internet security and oil and gas industries.

The OpenID Foundation is the standards-bearer for open, user-centric internet identity. I was one of the founders and served on the board of directors. Helped get it started, participated in the initial bounty program, and spearheaded customer research.

Helped frame the "Health 2.0" meme, starting at an unconference, and then with the founders of the Health 2.0 conference. Was advisor to the conference for about a year.

Alternate steward for the Open Source Identity System (OSIS) working group. The identity commons is a loose affiliation of identity-related projects with some common infrastructure.

Conceived, and ran OSIS (“Open-source Identity Systems”), an industry group that developed open, interoperable digital identity technologies until about 2013. To my surprise, I was able to recruited CA, IBM, Microsoft, Novell, Oracle, Verisign and others as active participants.

Started company to address unmet needs in the collaborative engineering software market: productivity web applications for geographically and organizationally distributed teams building integrated hardware/software systems. Conceived and built initial product LiveDoc based on a pioneering, model-driven Java P2P architecture. As the CEO, raised $3m+ in venture capital. Notable customers included BMW, DaimlerChrysler, JPL, TRW.

Initiated the real-time analysis and design (RTAD) effort in the Object Management Group. It brought together the OMG's Object Analysis and Design effort (which led to the UML) and the Real-time Special Interest Group, and produced substantial work over the next 10 years or so consistent with the original roadmap I had laid out. Recruited all major vendors of real-time analysis and design tools into the group. I stepped down to focus on my startup.

Hired by this Silicon Valley-based developer of modeling/simulation tools and real-time operating systems "because you know the requirements of automotive customers first-hand". Led design and implementation of modeling tools integrations and a CORBA-based co-simulation product. Component architect on a user interface framework and build system. Technical expert on many customer calls. Performed customer training in Europe and sales training. Represented company in several standards organizations (EIA, Object Management Group, ISO). Integrated Systems was later acquired by Wind River and is now part of Intel.

CDIF was an early semantic interoperability effort for software/systems modeling tools with participation from the chief architects of several high-profile modeling and repository vendors at the time. Initially I was involved to represent a consortium of European car manufacturers and influence standards for their needs as customers, but I continued this work after having joined vendor Integrated Systems. Editor of the State/Event Subject Area, initiator and editor of Control Systems Design Subject Area, and Editor of the Object-oriented Analysis and Design Subject Area. Was Vice Chair, Technical, for several years, responsible for technical work across working groups.

Performed contract research for companies such as BMW, Daimler, Volkswagen, Siemens, etc. in the areas of co-creation of specifications for electronic / software car components, distributed simulation, tool integration, cross-functional and cross-organizational development methodologies, and the OSEK real-time operating system.

BMW supported my master's thesis ("Dipl.-Ing. Elektrotechnik") and later funded a 100% position for me at the Universities of Erlangen and Karlsruhe. Working on cosimulation, rapid prototyping of hardware/software systems, development methodologies, supplier collaboration and others.
