NAME

whoami — Kohei Wada

DESCRIPTION

Software engineer based in Japan, working remotely. I started out plotting math in Python, picked up C for low-level and driver work while studying mechanical engineering, then moved through web development (PHP, C#) before settling into a Unix-style tooling stack of my own.

I publish taskdog, a CLI / TUI task manager built on Textual + FastAPI in a UV workspace monorepo, with the core, API, and UI split into separate packages and a written DESIGN_PHILOSOPHY.md. It has been featured on Terminal Trove and LinuxLinks, and Textual's author Will McGugan publicly called it well-designed for the terminal.

I spend most of my time around low-level, systems, and CLI work, with Neovim and Unix tools as my daily driver, and enjoy functional languages like Elixir and OCaml on the side. I also keep a Zettelkasten for technical and design notes, so structured fragments can be rediscovered and connected later.

I like automating the little frictions in everyday work — small shell scripts and CLIs that earn their keep over time.
