A curious mind.
A human touch.
I’m Junpei, a software engineer crafting apps that make everyday life a little simpler, closer, and more interesting.
Explore my workto the final little detail.
Ideas, made real.
A few things I’ve put into the world.
Open a project. Make yourself at home.
A familiar home for your apps, with the little utilities that make every day feel easier.
A playful space for two. Send a small “miss you” and make an ordinary moment feel shared.
A local-first workspace for agents, tools, and the ideas that take more than one step.
Exploring family stories, ancestral places, and the connections hidden between them.
Engineer by trade.
Curious by nature.
I like making complex things
feel effortlessly simple.
My path into software started with psychology. That curiosity about people still shapes what I build: useful tools, thoughtful interactions, and small moments that make technology feel more human.
Today, I work across native Apple apps, mobile experiences, web products, and the systems behind them. I care about the whole journey — from how an idea works to how it feels in someone’s hands.

Useful comes first.
Start with a real need. Make the path to solving it feel natural.
The details add up.
A shortcut, a transition, a well-placed word. Small things shape the experience.
Keep being curious.
Build, learn, rethink. There’s always a more interesting question to ask.
An idea, a collaboration, or just a hello.
I’d love to hear from you.
