AI-Driven Fullstack Developer Building AI-Integrated Web Applications

TypeScript React Next.js Node.js LLM Integration Type-Safe APIs

Building the next generation of AI-integrated web applications.

I’m a fullstack developer focused on turning LLM capabilities into usable products, not demos. My work sits at the intersection of modern frontend engineering, type-safe backend architecture, and practical AI workflows such as structured outputs, streaming responses, and prompt-driven product features.

Core Four

Project Focus One-line pitch
cangudev AI product workflow An AI-powered technical English coach that transforms developer text into structured rewrites, grammar feedback, idioms, and interview-style challenges.
youcanchef AI + UX A Gemini-powered web app that evaluates ingredient availability by city to help digital nomads adapt recipes with local-market intelligence.
cangu-finance Fullstack architecture A production-oriented TypeScript monorepo for mobile and web apps with typed APIs, auth, database workflows, and AI-ready backend services.
skillforge AI-ready platform engineering A full-stack TypeScript platform combining mobile, web, and streamed LLM interactions through a type-safe API architecture.

Technical Superpowers

Backend & Architecture

  • Node.js
  • Monorepos
  • Type-safe APIs
  • Hono and modern API backends
  • Auth and database integration
  • Scalable fullstack project structure

Node.js Monorepos Type-Safe APIs Hono Architecture

Currently Building

I’m currently focused on building AI-native product experiences with:

  • Streaming LLM responses for faster, more natural interfaces
  • Structured AI data pipelines that return reliable JSON outputs
  • Type-safe fullstack systems where AI features integrate cleanly into production code
  • Practical developer tools and web apps that make LLM workflows useful in real products

What I Care About

  • Shipping AI features that solve real product problems
  • Keeping frontend experiences fast, clear, and production-ready
  • Designing backend systems that stay maintainable as complexity grows
  • Using LLMs as part of strong software architecture, not as a shortcut around it
