The person behind Ultra.dev

I’m Keith.

I build with AI. Then I show you what happened.

I’ve spent more than 20 years at the intersection of technology and growth. Ultra.dev is where I share what I’m building, what I’m learning, and what I think about where all of this is going.

That means working software, experiments that don’t go to plan, and strong opinions about what these tools make possible.
