A little about me

Hi, I’m Kirk.

I’m a father, entrepreneur, and someone who learns by making things. Lately, that’s been storybooks, an affirmation app, and a game for my sons.

Some are small. All have taught me something.

Things I’ve made

Here’s what I’ve been up to.

A few projects I care about,
and the stories behind them.

AI · Web · iOS · Print Live

StoryStar

From an idea to a book on the doorstep.

I built the whole journey: story generation, illustration, editing, mobile reading, payment, and print fulfillment.

3D art · Web3 · CommunityShipped collection

Satoshi Apes

More than a collection. A full creative launch.

I worked with a 3D designer trait by trait, built the generative pipeline, explored AR, and led the launch and community work.

Wellbeing · iOS App Store

Roar

I made Roar to help people build confidence a little at a time. It helps me stay motivated when I use it, too.

Games · iOS App Store

Griddle

My sons were obsessed with Block Blast. I built Griddle to show them this is a magical time: don’t just consume—make something.

Human judgment · API Live

HeyHuman

StoryStar made me wonder how software could ask a real person whether creative work actually feels right. I built HeyHuman to explore that.

Community · Discovery Live

OutJev

Jev gave me something new to wrap my head around. I made OutJev to see what others were building and learn alongside them.

Events · Web productBuilt from experience

Fetti

After a decade in events, I wanted to connect the parts guests actually remember: the invitation, the photos, and the shared story afterward.

AI agents · SocialExperiment

Xitter

A working social space where agents can share what they made, learn from one another, and leave behind artifacts—not just conversation.

What I build with

A few tools.
A lot of making.

Codex is my daily driver. It’s where I spend most of my time turning ideas into things I can actually use.

I also work with Claude Code, Z Code, and Hermes Agent. I like trying different ways of building—the best way for me to understand a new tool is to make something with it.

A bit about me

Entrepreneur.
Father.
Still curious.

Usually making something.

I usually understand something better once I’ve tried to make it.

I’ve been an entrepreneur for most of my adult life. These days, I’m also trying to show my sons that the things they love don’t have to arrive from somewhere else—they can make them.

None of these projects has a giant audience. That’s okay. They’re real, people use them, and each one made me better at turning a loose idea into something that works.

I’m an American citizen and a world traveler, and I’m interested in roles that let me be based in the USA, Portugal, Nairobi, or Thailand.

The question on my mind now is how to keep growing as a builder, entrepreneur, and father in a world that changes almost every day.

Before these apps

A little more backstory.

Ten years of my life

Big Bad Booth

I built and ran a photo booth and events company for a decade before selling it. It taught me how much unglamorous work sits behind something customers can rely on.
