About me
I studied business and commerce at Keio University. I began my career at a systems integrator, then joined the in-house digital transformation team at an HR services company before going independent. Today I work as a freelance engineer, leading web application development projects.
Teaching is the other thread that runs through my work: I have designed training programs for new engineers, written the course materials, and taught the courses myself.
Personal projects
Hiyoko Playground
Hiyoko is a language designed to be a complete beginner's very first: only basic, widely shared syntax, the minimum set of concepts to learn, and nothing to install.
I designed the language, wrote the interpreter in Rust, and compiled it to WebAssembly so the playground runs entirely in the browser. The language implementation is on GitHub.
