About Henry

A builder for practical, AI-assisted software.

Henry Zhang is an independent developer focused on turning narrow workflow problems into polished web products. The work spans AI translation, browser productivity, creator media tools, developer utilities, and edge-first full-stack React applications.

  • AI Tools

    LLM-powered products that compress tedious workflows.

  • Browser Extensions

    Native-feeling utilities for translation and web productivity.

  • React / TypeScript

    Fast, typed interfaces with product-grade interaction design.

  • Cloudflare Edge

    Workers, D1, R2, and edge deployment for small, sharp apps.

  • Product Shipping

    From rough problem to public tool, docs, and iteration loop.

Featured Work

Products framed by the problems they solve.

Each project starts from a repeated friction point: translating faster, committing cleaner, clipping locally, or routing AI systems more efficiently.

What I Build

Small tools with a sharp edge.

The site is both a portfolio and a living product lab: public tools, technical writing, and experiments that make everyday digital work more direct.

Workflow lens

I prefer tools that remove a real step from someone's day: no-upload video utilities, private translation flows, local AI commit helpers, and browser surfaces that stay close to the page people are already using.
