About

I'm Gyo, a designer who builds.

I design and write the code for apps, digital products, and this site.

Apps and Projects are things I have made. Articles is where I write longer notes.

Articles are written from primary sources. When a piece describes how a system behaves, I read the code or run it before publishing, and the piece states what was verified and what was not.

This site runs on Next.js and Vercel. Content lives in Cloudflare D1 and images in private R2, so publishing does not require a rebuild.
