COOPER HU / HELLO
I spent nearly ten years working as an engineer in tech. I still write code, and AI has also pulled me into design and product work. Some of it is taking shape here; the rest is still being figured out.
Three references
Three yellow memories, from different places. The avatar arrived somewhere between them.

The grin that nearly fills the face.

A smile drawn into a yellow petri dish.

Found, eaten, and remembered in Japan.

One began as a way to notice yourself and start a quiet conversation. The other brings attention back to now when the world feels complex and hurried.
MOOD / MOMENTS / ECHO
Day in Five began with a simple thought: notice what is already here, then make a little room to answer yourself. It keeps a few mood moments you choose during the day—without diagnosis, streaks, or any requirement to feel positive.
ONE CARD / IN SIGHT / LOCAL
Current Card began as a small counterweight to a complex, impatient world: keep one thing visible, and let attention return to now. The same card can appear in a Widget, Live Activity, and StandBy, then be cleared when it is done.
02 / AFTER I LEFT
The short version is this.
I spent nearly ten years in engineering and got used to clear goals and pace. Later, focus became harder and the work became tiring.
It did not feel lighter straight away. I had no fixed schedule and no next plan.
I hosted a few small offline salons. Now I mainly make apps and keep learning design, photography, and tennis. AI is one of my everyday tools.
This site records only the part I am in now.
03 / A FEW JUDGMENTS
They may change.
Interfaces, words, and sound are methods. There is no need to add another layer just to make something look complete.
Seeing more does not automatically make judgment better. What stays and what is removed usually matters more.
It is useful for widening the choices, not replacing the choice.
04 / NOW
Day in Five and Current Card are both moving toward their first public versions. I’ll also add more work, notes, and photographs to this site.
05 / AWAY FROM THE SCREEN
In no particular order.
I occasionally host small offline salons. This site only mentions them; it does not publish events or take registrations.
Still learning. I’d like to become a dependable hitting partner.
I use a Fuji and like photographing people and everyday scenes. You can also ask me to take a few photos.
I’m planning to raise a small dog. Still looking for the right one.
Still learning English and Japanese, and slowly making room for other languages too.
