Editorial interest 88/100 Selection signal · not a rating of the site

A Japanese product engineer’s portfolio documenting a surprisingly broad run of social apps, games, educational tools, maps, databases, and small utilities.

Landing page captured for the 2026-09-10 issue.

Field notes

The project catalogue records both product concepts and implementation choices, making the page useful as a compact map of one maker’s working range. Examples include a 20GB registration-free file-transfer service, a historical interface combining time and geography, and a classroom coding tool that transpiles generated React code instead of executing it. The author also supplies a timeline from NTT Data to Tennis Bear and labels several entries as still in development.
