About

I’m Mark Hall, an AI engineer and full-stack developer working at GoEngineer. I enjoy turning ambitious ideas into software people can inspect, understand, and trust.

My current work explores local language models, agentic systems, Model Context Protocol tools, evaluation, and the engineering required to make AI useful outside a demo.

I’m also the creator of Sir Thaddeus, an open-source, local-first assistant for Windows with permissioned tools, durable memory, and evidence-driven small-model experiments.

This is my personal site. The opinions here are my own.
