I build AI-driven applications from idea to production. Four products are live — a legal AI platform, a Norwegian text-to-speech service, a parliamentary monitoring platform, and a democracy platform in development.
My specialty sits at the intersection of LLM architecture, multi-agent systems, and the full-stack work that actually gets them shipped — model training, internal infrastructure, eval pipelines, and the rest of what doesn't show up in a demo.
Legal AI platform that analyzes documents and legal questions with advanced LLM reasoning. Conversational case analysis built on a multi-agent architecture, with clear answers and traceable citations to Norwegian law, preparatory works, and case law.

Monitoring platform for Norwegian politics. Pulls open data from Stortinget and makes it searchable and alert-able — semantic search across speeches, votes, and proposals, with MCP integration so AI assistants can query the dataset.

Taking on a small number of consulting engagements each quarter — typically AI architecture, model infrastructure, or full applications going from idea to production.
