About JPK
After experiencing the full spectrum of development—from hands-on engineering to management—as a core team member, I took the leap and started my freelance journey in 2026. While I used to be based in Tokyo, the freedom from location constraints has allowed me to relocate to the beautiful city of Matsumoto in Nagano Prefecture, where I now operate.
My core philosophy is to 'work with joy.' I truly believe that for me to enjoy what I do, the team must be having fun, and our users must enjoy the journey just as much.
This site feels more like a space for self-expression than a traditional portfolio. If anything here resonates with you, please feel free to reach out—whether it's for a casual chat, shared interests, or a project. (Though, I certainly won't complain if it's about a work opportunity!)
