From Tokyo
to the world.

Web apps, MVPs, landing pages. Code that ships on time and still works a year later.

Code that ships
and keeps shipping

I build things that work. Then I make sure they keep working.

5+ Years

Building for startups and enterprise since 2021.

Japan-based

Async-first. Comfortable working across timezones.

Full-stack

React on the frontend, Spring Boot on the backend. I handle both.

Ship & Maintain

I care about what happens after the PR gets merged.

My Process
Step 01 Discovery

I go through the codebase first, then ask the right questions. Requirements get confirmed upfront so we stay aligned.

Step 02 Build & Iterate

Usually I start with one small task to prove I can deliver. After that, I move fast and share progress along the way.

Step 03 Ship & Maintain

You get code you can maintain without me. I refactor when it matters and keep things clean as I go.
