About
Will Macdonald

MedTech advisor in Chicago. Most of my work sits at the seam between AI models and the workflows they were bolted onto — manufacturing operations, regulatory and compliance, supply chain, and the long tail of things that quietly break in the second month after a pilot ships.

The coding here is so I understand the boring half of generative AI well enough to advise on it. I work on agentic systems, eval harnesses, and the integration plumbing that decides whether a pilot survives past the demo. When the model is the easy part, I'm interested in the rest.

When I'm not coding or advising, I'm in the kitchen, in the workshop, or behind a camera lens.
