Employee of Krummholz AI LLC.

Krummholz AI LLC · 17A Main St, Belfast, ME 04915

I build datasets and software for work that happens outside the lab. Krummholz is currently based in Belfast, Maine.

At Krummholz, I lead data curation and engineering for applied AI, with a focus on forestry, fisheries, customer service, and practical robotics. Our work includes synthetic data and open-weight LLMs. User-reviewed learning remains in development. I also build outdoor apps and custom business software.

My background includes work at the South Dakota State Data Center from 2013 to 2018, along with web development, CRM systems, and AI data workflows. Away from the desk, I'm usually hiking or climbing, often on Maine's trails.
