Hi, I'm

Software Engineer / Creative

Profile

A software engineer who loves programming and creative work.

Primarily focused on web backend development, I also work broadly on language processing, tooling, and slide creation. Thinking through ideas while walking is a daily habit.

I'm interested in the design philosophy of programming languages and type systems, and I enjoy working with Rust, TypeScript, and Haskell.

Even after coming out from the island of Octopus Tree to the capital of flowers, this tendency shows no sign of changing. Perhaps the South Seas daze has not yet worn off.
