Hi, I'm Yuki.
I'm a researcher who builds.
I study how people decide and learn. I measure what they can't put into words.
Attention, motivation, stress: I read them from behavior and biometrics, not just self-report.
I pair that signal with interviews and field observation. Quant and qual, one picture.
When a study needs a tool that doesn't exist yet, I build it.
The findings change what gets built.

Subscriptions I Forgot I Had
I have more than 20 subscriptions. In the last six months I've been on the phone with platforms and credit card companies five times over charges I didn't want. That was in the last six months alone.
The apps that cancel for you break the moment a site changes its flow. This one doesn't click for you. It finds what you're paying for, pulls the current cancellation path, and drafts the email when an email is what it takes.
The model runs on your machine. Your mail is read locally and never uploaded.
Now: testing how accurately a local model can identify subscriptions from receipts.
