02 / Behind the work

The person
behind Rootlet.

Hi, I’m Don. I’m a radiologist who spends a lot of his free time building software. Rootlet Studio is where I share what I make.

I like taking things that already work and finding ways to make them better. Sometimes that means a clearer screen or a simpler interaction. I enjoy working through both the design and the code.

Make the next step clear.

Start with what someone came here to do. Then give them an obvious way to do it.

Keep the pieces consistent.

A design system gives every screen the same foundations. A control that looks familiar should behave that way too.

Build components to reuse.

A button belongs to the whole product. Get it right once, then use it wherever it’s needed.
