Independent studio · California

One desk, two cats, and a rule about what ships.

We are independent on purpose. You’ve probably met us in the photo already. We stay close to the work so we can go deeper on the ideas that deserve it. AI changed what an independent studio can do: explore more ideas, prototype them in days, and learn quickly which ones should ship. Most experiments stay experiments. Nothing leaves this desk until it shows its work, keeps private work private, and holds up under our own daily use. Not before.

Who’s behind it?

Hi. I build from what I learn.

I build from problems I have lived with or seen up close. There are four apps because four problems have earned the work so far. The next one ships when I run into it. Not because shipping is easy now.

Before DZG STUDIO, I spent about a decade in data science and applied research, across academia and fintech: a university transportation lab, then data science at a bank, a brokerage, and a payments company. The habit that stuck wasn’t a build process; it was asking whether the evidence actually supports the claim. Scene’s deliberately smaller promise and Mint’s ask-before-acting design both come from that habit.

These days the studio is me plus a stack of AI coding agents. 72.6 GB of them on disk at last measurement, so no romance about the typing. The agents make code cheap. They don’t decide what deserves to exist, and they don’t answer your email; I do both. The products are serious; the studio still feels like a real life, and every long session has someone to lean on.

How I work

Useful first. Quiet when possible.

The DZG in DZG STUDIO comes from the Chinese phrase 动真格 (dòng zhēn gé): don’t just talk about it, actually do it. Design with Zeal and Grace is the English take on the same idea. Zeal is the daring part: take the idea seriously and build it for real. Grace is the care: get the details right without making them someone else’s burden. Day to day, that is where the time goes. Four rules I don’t ship without.

  1. 01

    Show the work

    When software can move, clean, or interpret something important, you should be able to inspect what it is about to do. Receipt: On-Device Intelligence ↗

  2. 02

    Keep private work private

    Use the Mac in front of you whenever possible. Do not turn personal work into training data. Receipt: The Whole Route Stays Local ↗

  3. 03

    Refuse well

    What a product declines to do is part of the product. Scene promises less than a full rollback because the evidence stopped there; Reso cut 20% of its features to protect the foundation. Receipt: Scene’s evidence ↗

  4. 04

    Stay close enough to listen

    Product questions and useful feedback reach the person making the decision, not a maze of departments. Receipt: the Contact page, one email address
