HStewart23/README.md

Applied AI builder and facilitator. I build production LLM systems at the Ellen MacArthur Foundation, where I led the organisation's Claude rollout, and I design embodied workshops that help people understand AI by enacting it.

Most of my recent engineering work lives in the Foundation's private repositories. The public evidence is the technical appendix to Circular by Nature (EMF, 2026), documenting a RAG pipeline I designed and built for national policy analysis: GROBID parsing, FAISS retrieval, and a hierarchical roll-up architecture validated against ground truth.

Elsewhere: The Simulation Game, an embodied AI ethics workshop (DOI: 10.5281/zenodo.21397412) · hstewart23.github.io
