About
Software engineer.
Builder.
From Japan.
Hey, I'm Atsushi.
I'm a software engineer from Japan. I quit my full-time job in August 2025 to build products of my own, and I have been doing that ever since — unevenly, and alongside contract work that pays for it.
The first one was One New Friend, an anonymous chat app that reached about 3,000 installs and peaked near $48 MRR in October 2025. Then it churned back down. That taught me more than building it did.
My goal is a portfolio of small, profitable products that let me work from anywhere. I am a long way off. This site publishes the real numbers on the way there, including the months they go down.
