Hello. I am Chris Mueller

I’m a UX designer based in San Francisco, California. I focus on information architecture and design systems, but I especially enjoy whitespace, consistency, and solving problems.

Check out some of my work below and feel free to get in touch. Oh, and here's my resume.

In-line commenting on structured data

As you may expect, NASA engineering data gets reviewed a lot, requiring the owner to merge and address comments from tons of documents.

We sought to reduce this effort by developing a mechanism for having review discussions directly on the newly centralized, structured data being reviewed.

Improving digital signatures

Boy, NASA sure loves making people sign documents. Because of this, the need for functional digital signatures is real high.

Our previous interface for digitally signing data needed improvements, so we re-designed the interactor to be easier to use and understand.

Digitizing complex test setup

The Ames Arc Jet Complex tests vehicle heat shielding by simulating flight- and re-entry conditions.

Working with the Arc Jet team, we created a desktop and mobile web application to improve their test setup process by reducing errors and increasing worksheet completion.

Head-mounted procedures (in space!)

Astronauts on the International Space Station follow pre-written procedures for pretty much everything. Those procedures, and the mechanism for viewing them, have many drawbacks.

As a graduate research team, we built a head-mounted procedure viewer prototype to help maximize crew efficiency.
