Introduction / 自己紹介

After completing a master's degree in mechatronics at a New Zealand university, I worked in the research laboratory of a major general electronics manufacturer in Japan. I was engaged in the development of a cloud-based information infrastructure system that supports policy decisions to improve the design accuracy of machanical structures and optimize operation and maintenance plans by utilizing machine operating IoT data.

Then, I transferred jobs to the advanced development department of a Tier 1 automotive supplier and engaged in planning, development, and prototyping of electric powertrain systems.

Further after that I working for a start-up company specializing in 1D CAE contract development and consulting, became independent as a professional engineering office in mechanical accredited by the Japanese government.
