About

Engineering with judgment, not ceremony.

I’m an independent software engineer based in Tokyo, working across product, platform, and cloud infrastructure.

How I work

I like ambiguous problems, small capable teams, and systems that remain understandable after launch. My work moves between technical direction and hands-on implementation.

The thread through it all is clarity: in architecture, interfaces, documentation, and the decisions a team has to live with.

What I care about

  1. 01Useful software over performative complexity
  2. 02Systems that are observable and operable
  3. 03Interfaces that respect people's attention
  4. 04Documentation as part of the product
