About

I’m Eshin Kunishima. This is my personal site, where I write about infrastructure, networking, and whatever I’ve been taking apart lately.

Recent writing covers serving static files through Cloudflare Workers, and reverse-engineering the regulatory logic in a DeFi frontend. Most posts are in English; some are in Japanese.

I also build and host a few small browser tools — see Apps.

Find me on GitHub as @mikoim.
