About

I am a university student majoring in information technology in Japan. From next April, I will work as an engineer in Japanese company. But, I wanna work in foreign country except Japan in the future. I wanna offer from foreign company. My dream is to build apps that make people around the world happier and create a real impact.

Readable Code - Practice writing code your teammates can actually read

Readable Code is a training app for writing code people can actually read. Working code and readable code aren't the same. Rewrite messy TypeScript snippets, then get scored on naming, structure, simplicity, and comments—with concrete feedback. Great for engineers whose code gets flagged in review, juniors, and anyone prepping for interviews. Practice fixing bad naming, magic numbers, deep nesting, bloated functions, and lazy any types. Pick a difficulty, submit, and beat your best score.

Flight Overhead - Maps overhead aircraft live, alerts when planes are near you

Unlike broad flight-tracking apps showing global traffic, Flight Overhead focuses on what's flying above you, right now. It auto-detects nearby aircraft, highlights the closest plane, and shows aircraft silhouettes for quick ID. A standout feature is proximity notification: alerting you when a plane enters a 40km radius, turning curiosity into an active "look up" moment. The experience stays clutter-free—no fleet tracking, no schedules—just a fast answer to "what's flying above me?"
