Hey, I’m David.

I’ve worked in technology, real estate, and a small products business. I like getting into how things work, asking questions, and finding a useful way forward.

This is a mix of projects, experiments, and a few detours along the way. I’m sharing the working-out along with the finished bits.

Things I’m making & figuring out

A few things on the desk.

What should a warning actually tell you?

Yes, the chocolate kind.

An unexpected chapter

There were fountains, too.

I co-managed a specialty beverage and chocolate fountain business. Product questions, sourcing, the website, and getting orders out the door were all part of it.

It’s one of the chapters behind this mix of interests. On the About page, I’ve kept an archived storefront image and the original product guide.
