Software architect. AI development pioneer. Community builder.

30 years building software, communities, and organizations. Co-founder of JavaZone and founder of eXOReaction. Java Champion since 2005. Based in Oslo.

These days I'm focused on what happens when experienced architects work with AI -- not just alongside it.

  • What If Your Organisation Remembered? People, Agents and the Conversations That Compound

    A post for leaders, not engineers: what it would mean if your organisation kept the conversations between people and AI agents as one signed record, let agents read, filter and draft, and still made every decision a human act. What we have already done among ourselves, what you could get, what it costs you today, what is not built, and why 10-40x appears here only as a hypothesis with a measurement plan, never as a result.

  • Prose, a Line of Dashes, Then JSON: How Agents and Humans Talk on Sunstone Atlas

    What literally goes over the wire when agents and humans coordinate on Sunstone Atlas: one signed line per event, prose, a dashed sentinel, then JSON. Channels versus groups, one agent message dissected, the same door for people and daemons, chunking and the 49,031-character plan review that tripped our planted bug, what the signature proves and does not, and what is designed but not built.

  • Agentic Engineering Teams on Sunstone Atlas: What They Are Made Of

    What an agentic engineering team on Sunstone Atlas is made of, part by part, each tagged by how built it is: identity, signed channels, co-workers, review, human gates, workflows. Including what does not exist yet. The first of two posts; the second is the experiment where we used all of it on ourselves.

What I'm working on

  • Skill-Driven Development

    A methodology for structured AI collaboration that compounds daily. Six pillars. Proven 25--66x productivity gains across manufacturing, finance, energy, and security.

    About eXOReaction

  • Synthesis · v1.42.0

    Local-first knowledge infrastructure platform. 76 CLI commands, 52 MCP tools, 4,700+ tests. Indexes workspaces, builds multi-layer knowledge graphs, exposes episodic memory and Notion integration to AI agents.

    Knowledge Infrastructure · Open Source

  • Knowledge Context Protocol

    A YAML standard that makes knowledge navigable by AI agents. Topology, intent, freshness, audience targeting. Submitted to the Linux Foundation's Agentic AI Foundation alongside MCP and AGENTS.md.

    Knowledge Infrastructure

  • lib-pcb

    A complete PCB design file processing library in Java. 8 format parsers, 28 validators, 17 auto-fixers, manufacturing-ready Gerber output. The project that proved SDD at scale -- 197,831 lines in 11 days.

    Open Source

  • Xorcery AAA

    Temporal analytics and DevSecOps intelligence platform built on the Xorcery reactive framework. Tracks vulnerability lifecycles, answers "why did this break?", and automates compliance -- without cloud lock-in.

    Open Source

  • Quadim

    A competence management SaaS platform. Helps organisations map, develop, and visualise the skills of their people. Built with the same AI-augmented methodology as lib-pcb.

  • Workshops & Training

    Hands-on SDD workshops for development teams. From full-day intensives to multi-week mentoring programs. Real code, real methodology, real results.

    Get in touch

  • JavaZone & Community

    Co-founded JavaZone in 2001 -- now Scandinavia's largest developer conference with ~3,000 attendees. Communities are where real knowledge transfer happens.

    Organizations

The proof

In January 2026, I built lib-pcb -- a complete PCB design library in Java.
197,831 lines of Java
7,461 tests (99.8% pass)
11 days total build time
10--18 months industry standard

8 format parsers. 28 validators. 17 auto-fixers. Manufacturing-ready Gerber output. Zero AI-induced production bugs.

This was not magic. It was methodology -- Skill-Driven Development applied systematically with Claude Code. The kind of thing I write about and teach in workshops.

Speaking

Conference talks on architecture, productivity, and development methodology. JavaZone, JavaOne, NDC, and more.
