Developer at Eccera AS. Based in Steinkjer, Trøndelag, Norway. Remote.

I build platform tooling for AI-assisted product development. The problem Mycelium exists to solve: AI agents are great at building, and terrible at knowing what to build.

Active projects

• Mycelium. Product-development harness for Claude Code: 61 skills, 13 theory gates, fractal diamonds. MIT. ⭐ 45.
• ux-axioms-mcp. An MCP server exposing UX axioms as first-class tools and resources for AI clients. Apache-2.0.
• ntrax (source private, public issue tracker). A browser-based modular music tracker. Mod-tracker precision meets modular-synth flexibility. Early beta.

Focus areas. Agent-assisted product discovery and delivery. Model Context Protocol servers. Developer experience and IDE tooling. Stack: Python, TypeScript, Swift, React.
