# Henry Zhang's Digital Workshop / 张赫的数字工坊

> AI tool builder and independent developer shipping practical browser extensions, developer utilities, creator tools, and edge-first React applications for real workflows.

Henry Zhang, whose Chinese name is 张赫, focuses on practical AI-assisted software: privacy-first translation, browser productivity, client-side media processing, developer tooling, and Cloudflare-backed full-stack React applications. The site is intended to be readable by people, search engines, and AI answer engines.

Core topics: AI tools, browser extensions, React, TypeScript, Cloudflare Workers, D1, R2, WebAssembly, developer tools, workflow automation, technical writing, independent software products.

## Languages

The canonical English site keeps the original URLs. Simplified Chinese core pages use the `/zh-CN` path prefix. Product pages, product privacy pages, home, about, sponsor, and the product index have translated main content. Blog posts, tag pages, and the blog index are default English URLs until Henry publishes real translated article content.
