Opportunity Fit

With a deep technical, interpersonal, creative, and business background, I fit a wide range of roles.  
I am looking for the best overall opportunity & challenge: Organizations with important purpose & goals requiring uniquely multifaceted, deeply skilled technical talent.  Most suitable roles: lead architect & developer, hands-on CTO/CIO/CISO, VP/director of engineering / SW development / R&D, or related consulting.  I am broadly open to mutually interesting suggestions.


This is a concise summary; full version available.  As a technology enthusiast, I have deeply explored most related topics.

Recent Activity

For the last 5+ years, deeply involved in current SPA (single page web app) & scalable cloud technology, developing a complex integration of 3D game engine (WebGL, ThreeJS), 3D editor, video, rich text editing, slides, and scripting in a highly responsive web app using web components.  Several tools and approaches have been published as open source: Merkle Hash web cache builder, completely new panel responsiveness system, async module loading system, Docker, websockets, graph database based app stack.

In parallel, bootstrapping a new approach for robotic actuators, self-filed a patent & mechanical design; forming a large ANA Avatar XPRIZE contest team creating an avatar system: remote telerobotics for home health & elder care, travel.  Performed deep & broad research, attended trade shows, and established partners.  
Working with Linux, ROS, ROS2, WebRTC, WebSockets, Oculus Quest, mechanical design.

Past experience includes: deep mobile development (Android), cameras & imaging, ebook readers, scalable server apps for millions of users, secure app dev, insurance quoting, banking, encryption, PKI CAs, various databases, protocols & standards work (IETF, W3C), and embedded factory machine control.  I’ve run my own servers with DNS, email, web, usenet, and apps on the Internet since 1992.  AI, ML, vision, and NLP have been deep research interests for decades, intersecting certain projects.  I’m a bit of a legal geek, especially IP.  

Computational imaging array camera integration, optimization, and product development.  Google Mobile Android (Java/C++) and desktop Qt (C++) programming, Java/C++/JNI, XML, web services, rendering.  Vision recognition.  Cray XT3 installation, repair, mgmt.  Patent consulting.  Stealth knowledge organization startup.  CPU simulator visualization.

Soft Skills

My purpose of life: Make myself useful by making the world a better place in whatever large and small ways that I can, so that my journey has been worthwhile.  How does your mission enable that?  How are you significantly improving the world?  Is there a way that I can play a key role?  Some of my recent goals and activities have been toward: greatly improving education & job prospects for blue collar workers and everyone (Yebo / Change My Path, Blue Scholar Foundation), solving commute & worker shortages while enabling disabled freedom through telerobotics (VolksDroid), creating a true usable visual knowledge base (VKMaps) to allow people to better capture, organize, and share all information, and writing a pair of books to improve lives & society.

I continually learn, grow, and transform, adjusting my goals to fit available opportunities and perceived best use of my abilities.  I have an extremely deep and diverse range of experience, skills, connections, and interests.  I’m well-rounded, self-sufficient in broad ways, and internally driven in multiple senses, always considering and tracking a stream of options at all levels.  I am continually creative & inventive, frequently synthesizing new approaches, ideas, and solutions after I thoroughly understand a new area.  I rapidly absorb and adapt to new environments, technology, people, and culture, adopting both enterprise and customer problems as my own, and rapidly internalize constraints and available tools to productively solve problems and answer needs.

From my early teenage years through today, I have had broad curiosity, voraciously reading & researching an extremely wide range of topics.  This broad awareness, coupled with my diverse work experience, often gives me unusually useful creative insights.  I have had enough consistent success to be confident I can bridge gaps in most cases, and enough mistakes and difficulties getting there to usually avoid being overconfident or truly arrogant.  I do however fearlessly take on difficult projects, problems, and environments and am generally confident that I can ramp up and innovate as needed.  This is fun for me.  I am highly cognizant of Dunning-Kruger.  I have raised several children, including adopted, the last two as a single father since my youngest was 12.  I repeatedly coached & refereed sports and academic teams, volunteering in various ways.  I have worked with a very large number of coworkers & customers, performed deep technical screening & interviews of hundreds, and have mentored many.  I have managed teams of 20+, coaching teams formally and informally.  I am adept at resolving conflicts between people and excel at debugging complex problems within complex systems.

I am very healthy, running multiple half marathons and other races every year, biking, mountain hiking, kayaking, sailing, and inline skating.  I have run at least 20,000 miles.  I am a private pilot (haven’t flown for a while), PADI scuba certified, used to rock climb, and ski & snowboard.  I am an avid semi-pro photographer: over 100,000 photos taken globally, including at night in the street on skates in Tokyo at 20mph.  The day before I spoke at a conference in Montreal, I walked 43 miles taking pictures.  All of this has contributed to and illustrates my stamina and energy on projects that I focus on.
