Hi! I am a software developer residing in Shonan, Japan.

My current specialty is web application development using Ruby on Rails, React, Next.js. I love writing code, but I also like to think about design and business.

Since I have experience from infrastructure to application development and design, I am good at looking at the entire system and designing the best solution.

I also have a lot of opportunities to work directly with executives, so I am well versed in business.
