A small collection of things I’ve built, explored, and occasionally finished.
PROJECTS
A few things I’ve made.
Lumi
An iOS app that turns your camera into a flash-card builder for Japanese. I was tired of using an Apple shortcut that applied the same logic (take photo, OCR, copy text, and paste to a URL to process). The app manages the whole chain and is faster, easier to use, and builds in the flash card system natively.
View project →Readout
A website to view earthquake, flood, landslide etc detail within Japan. If you're ever looking to buy or rent in Japan, this site allows you to easily see the collated data in one panel. Data comes from official government sources, and is easy to use compared to the Japanese equivalents.
View project →Differ
Differ is a high-performance Kotlin object diffing library that generates type-safe comparators at compile time using KSP. By turning comparisons into ordinary Kotlin code, it avoids reflection, JSON trees, and runtime interpretation — making object diffs extremely fast.
