Dan Haggerty

Full stack developer based in Detroit, Michigan.

Hey, I'm Dan. I'm a full-stack developer, home improvement enthusiast, and new hire at NVIDIA working on UI for LLM apps. I recently resigned from Twitter where I worked on content moderation tools. I specialize in React, Typescript, and just generally building polished UIs. Aside from all that, I'm usually working on my house or out on the lake.

I'm not looking for work right now, but feel free to contact me anyways.
