Tools I build.
Code you can use.

I build tools for the work I do: collecting better feedback, running coding agents, starting new products, and reading docs. These are a few of the projects I share in the open.

In-app feedback

lightback

Let users point at an element, add a note, and share a screenshot. Capture the surrounding context so developers and AI tools can understand what happened.
