about
Software engineer. Rochester, Minnesota. Currently focused on agentic systems in healthcare.
I build web applications.
And the agents that run inside them.
I have been shipping software professionally for a long time. Most of that work has been web applications on top of Go and TypeScript services. The last two years have shifted toward agentic systems — tool-use loops, context engineering, eval harnesses — usually inside a larger application, usually in a regulated domain where PHI and audit trails are first-class concerns.
what I do
Web applications
Full-stack web applications, mostly Go or Rust on the backend and whatever the frontend needs to be — React, Next, Svelte, Leptos.
Agentic systems
Tool-use loops, orchestration, and the harnesses around them. In-tenant Vertex AI and Anthropic, PHI-safe pipelines, real evals.
Context engineering
The work of giving a model the right material to do its job — retrieval, state, tool schemas — without turning the prompt into a wishing well.
how I think about this stuff
An agent that works is an agent whose control loop you can draw on a whiteboard. The interesting parts are not the model calls. They are the state machine around them, the tools you chose to expose, the eval harness that tells you whether the last change made things better or worse, and the observability that lets a human intervene before a small problem becomes a big one. The model is a component. The system is the work.
