I graduated with a degree in Mechanical Design and began my career in 2012 as a QC engineer in the workshop. I worked my way up through CAD engineering and eventually served as Chief Technical Engineer. I joined Shinjo Co in 2016 and have since focused on control valves and a wide range of challenging process conditions, supporting numerous overseas clients with demanding applications.
Over the years, I have come to believe that quality and solution capability are what ultimately maximize value — for both the client and the company. We welcome complex and unconventional cases. I hope my industry experience can be of help to you.
