I build intelligent AI systems
AI engineer and consultant. I help teams ship AI systems that hold up in production — and I'm currently rebuilding this site as an explorable 3D world.

This site is the portfolio — a game-quality 3D world with an AI digital twin, rebuilt in public. Built on React Three Fiber and the three.js WebGPU renderer under a strict progressive-enhancement contract: every visitor gets a working experience, down to a 2D shell that search engines and screen readers fully understand.

The site answers questions about Josh in his own words — a digital twin that speaks _about_ him, never _as_ him. It streams responses from Claude on AWS Bedrock through a Lambda response stream, grounded in a fixed persona plus the same public corpus that powers the rest of the site, so the twin and the portfolio can never drift apart.

Leading engineering on AI-assisted bidding workflows — the retrieval, the language-model pipelines, and the platform that has to stay up around them. The interesting work is making LLM features behave in production: grounded, tested, and honest about their failure modes.
