Timeline

How the work moved.

My career does not read as a sequence of jobs: from 2000 onward my own studio ran continuously alongside employment, contracting, founding and consulting work, and the roles overlap by design.

Milestones

1990 to 2026

  1. 1990

    An industrial band in Denver

    I composed and played keyboards in an industrial band in Denver from 1990 to 1992.

  2. 1992

    An earthquake kiosk at CU Boulder

    At the University of Colorado Boulder I wrote an earthquake monitoring kiosk in C on Atari ST hardware so geophysics researchers could review seismic events themselves.

  3. 1993

    Interface Oblivion

    I played keys in Interface Oblivion, wrote the backing tracks and about half the compositions, and we put out several albums.

  4. 1994

    Reel Illusions

    I co-founded Reel Illusions in Boulder in 1994 and delivered enterprise multimedia applications for airline, banking and private-sector clients.

  5. 1994

    A seismic monitor for USGS

    I wrote a real-time seismic monitor in C on an Atari STE while I was a student at the University of Colorado, plotting earthquakes onto a colour topographic map as they happened and paging out alerts. I date the start of my technical career to 1994, when I released the seismic monitor.

  6. 1996

    Print and product design at MPH

    At MPH Strategic Brand Communications in Boulder I was the in-house digital production expert, producing print-ready artwork, product visualizations and photo art direction, and running four-colour press checks.

  7. 1997

    Leading multimedia teams

    As lead multimedia developer at Digital Creators from 1997 to 1999 I led teams through more than ten educational and corporate titles, and personally produced the storyboards, specifications, 3D models, animation and music.

  8. 2000

    Lumeneo Studios

    I founded Lumeneo Studios in 2000 and have run it ever since as the vehicle for my client work, taking engagements from concept through deployment across web, mobile, XR, kiosk and desktop.

  9. 2000

    San Francisco

    I moved to San Francisco in 2000 with the band and spent about twenty years in the Bay Area underground electronic scene, playing breakbeat, dubstep and drum and bass. My career does not read as a sequence of jobs: from 2000 onward my own studio ran continuously alongside employment, contracting, founding and consulting work, and the roles overlap by design.

    At Laszlo Systems I worked on Rich Internet Applications in Flash and played a crucial part in acquiring the company's first paying client.

  11. 2004

    Addictech

  14. 2007

    Lossless downloads

    Addictech sold its catalogue as MP3, FLAC and WAV downloads. Addictech sold music without copy protection while most stores still locked their files, and it sold lossless files at a time when almost nobody did.

  20. 2013

    Flash to HTML5, fifteen engineers

  26. 2021

    A donation ledger you can check

    As chief technology officer at Green Wings Compassion I architected a donation ledger on Chia DataLayer with on-chain Merkle snapshot verification, so a donor could check that a disbursement actually happened.

  27. 2022

    CHIP-0015

    I authored CHIP-0015, the NFT metadata standard for the Chia blockchain, which defines how a Chia NFT stores and references its data and builds on Schema.org.

  28. 2022

    SumSet Tech

    I founded SumSet Tech in 2022 and run it as my consultancy for blockchain, spatial computing and AI work, from smart contracts and NFT infrastructure to Unity AR prototypes and local LLM stacks.

  29. 2022

    CHIP-0021, composable NFTs

    I am lead author of CHIP-0021, the Fusion standard for composable NFTs, which lets assets be combined, split and remixed while their provenance survives every transformation.

  30. 2022

    NFTr.pro

    I founded NFTr.pro and lead its development, building the reference implementation and minting tools behind the Chia NFT standards I authored.

  35. 2024

    The Metaverse Metadata Directory

    I wrote the initial concept and the first versions of the Metaverse Metadata Directory, an open hub that maps how established 3D, spatial, identity, and content-authentication metadata standards fit together.

  36. 2025

    A second working group, and outside corroboration

    I am also a Working Group Chair of the Forum's AI x Metaverse Working Group. OMA3's June 2025 newsletter named me a co-chair of the Digital Asset Management group, as it was called then.

    I built Fusion, the technology behind FusionZoo for the MonkeyZoo project on Chia, which merges NFTs and supports peer-to-peer trading.

  39. 2026

    Universal Manifest begins

    I started the Universal Manifest repository in February 2026 and opened its public history in May 2026.

  40. 2026

    OMA3 takes it up for review

    I created Universal Manifest, an open specification for portable signed context that moves with people, agents, devices, assets, facilities, and infrastructure instead of being locked inside one system. OMA3's Technical Working Group took Universal Manifest up for review for potential standardization, as OMA3 stated in May 2026.

  41. 2026

    v0.4 and its conformance suite

    On 9 July 2026 I published the Universal Manifest v0.4 document set together with its conformance suite, in a public Apache-2.0 repository.

    Local Artist Network goes live

    Local Artist Network runs a live public browser catalog with artwork browsing, collections, places and schedules, and a display mode for venue screens. Local Artist Network aims at community-level creator visibility, venue integration, and local revenue pathways, built around a Boulder venue network using displays, streaming, and events.

  43. 2026

    EverArchive

    EverArchive is built to preserve the creative process, attribution, and cultural heritage over very long horizons, with a 200-plus-year design target. EverArchive is the Distributed Creatives preservation program and I am on its project team; it is in architecture design and partnership outreach, with prototype work later in the roadmap.

  44. 2026

    PeerMesh and Peers.social

    In 2026 my public commits landed across the PeerMesh core stack, its integration tests, the spatial fabric, the documentation, and an example module. PeerMesh is an open source initiative whose repositories are owned collectively and added to by everyone, with modules submitted by third parties and by the internal team. Peers.social is the tentpole implementation of every PeerMesh module in one system, with a creative community and builders making a network of federated websites.

  45. 2026

    The SaveTheCreators Hub

    SaveTheCreators argues creator rights across disciplines: consent, compensation, attribution, and preservation. As of August 2026 the SaveTheCreators Hub published 521 sourced items across 43 creative disciplines and 5 issue areas.
