software engineer
I’m a software engineer based in Japan. I love building open-source tools for developers.
I created
Repomix,
a tool that packs your whole codebase into a single AI-friendly file. I also make
Slack Channels Grouping,
a browser extension that keeps your Slack sidebar tidy, and
Tech Blog RSS Feed,
a daily-updated feed of Japanese tech-company blogs.
Away from the keyboard, I live with a cute dog —
Loco,
a rescue chiweenie and a professional napper.
📦 Repomix is a powerful tool that packs your entire repository into a single, AI-friendly file. Perfect for when you need to feed your codebase to Large Language Models (LLMs) or other AI tools like Claude, ChatGPT, DeepSeek, Perplexity, Gemini, Gemma, Llama, Grok, and more.
