Andrew Millspaugh

I build software and lead engineering teams. My work has included AI infrastructure, zero-knowledge cryptography, bioinformatics, and materials science.

Current work

Brassboard

Using LLMs for design problems that don't fit neatly into a conventional optimizer. The basic loop proposes a design, evaluates it with whatever models, simulations, tests, and engineering tools are available, then feeds those results into the next proposal.

Applications include materials, drug candidates, PCBs, and assemblies with many interacting parts.
