After graduating from university in 1996, worked for a major system integrator for 12 years and participated in various small and large system development projects.
As a project manager and engineer for development projects, worked on solving client’s problems.
During that time, I dealt with the programming language Ruby, and based on its innovativeness, I could sense the possibilities it held for me as an individual in the future. In 2008, I left my position as a manager with ITOCHU Techno-Solutions Corporation to become an independent freelance Ruby programmer.
After becoming independent, to date I have been involved in the launch and development of several web services/web systems using Ruby / Ruby on Rails.
My hobbies are playing soccer/running marathons/reading.
In 1973, born and grew up in Japan.
Residing in Machida City, Tokyo.
Father of a son and a daughter.
