About
I have been programming since the early days of home computers, and that is what my whole career has been built on. I am based on the Shimabara Peninsula in Nagasaki, in the southwest of Japan, and work remotely on projects across the country.
The open surroundings here shape how I approach a problem, and I put that into building software that holds up over time.
My strongest area is web services built around AI, backed by long experience in image processing and video systems. If you have a project in mind, the contact form is in the menu at the top right.
