AI product engineering
Browser-based coding agents, enterprise knowledge systems, workflow automation, and practical LLM application delivery.
ichuan
Full-stack / AI Product Engineer
I build production web, desktop, mobile, AI, and infrastructure projects end to end, with a bias toward usable tools, self-hosted systems, and fast product iteration.
Current Focus
Local + cloud tools
Self-hosted gateways, native desktop utilities, PWAs, deployment pipelines, and privacy-conscious product defaults.
End-to-end prototypes
From rough idea to usable product: frontend, backend, device integration, cloud deployment, and operational notes.
Systems background
Earlier work in wallets, exchanges, scanners, Web3 contracts, and security-oriented business systems.
Recent Projects
Portlight
Public HTTPS tunnel for local HTTP apps: expose a localhost port, get a shareable URL, and use it for previews, demos, webhooks, and agent workflows.
Birthday Pet
Personal-use Windows desktop pet voice assistant turned into a releasable product, with character animation, click-to-talk, spoken replies, web search, memory, and controlled backend access.
Agent Pad
Self-hosted browser gateway for using desktop AI coding tools remotely, designed for working across home machines, tablets, and cloud-like workflows.
Cloud Agent
Web-based AI software builder that turns product ideas into runnable web applications with planning, preview, file inspection, and deployment flow.
VIP - Voice Input Pro
Minimal cross-platform voice input tool for Windows and macOS, built for daily low-friction dictation into any active application.
Terra Drive
Autonomous mower prototype combining cloud task management, onboard navigation, RTK/LiDAR sensing, and safety-oriented remote supervision.
Notes
Modern note-taking web app with rich text editing, search, sharing, AI chat over notes, and production-minded security defaults.
Motion Games
Browser-based motion interaction game collection using the camera as input, with no external device required and bilingual Chinese/English support.
Translator
Minimal English-Chinese translation PWA with automatic language detection, grammar correction, installable app behavior, and server-side API key protection.
MailMail
Privacy-focused native Windows 11 email client built with Tauri v2, Rust IMAP logic, React UI, and offline-first local rendering.
Experience Highlights
Enterprise AI systems
Built internal knowledge-base and QA systems at multi-million-document scale, including ingestion, retrieval, ranking, chat UI, and deployment.
AI software platforms
Built browser-based tools that turn product concepts into runnable applications with planning, preview, execution, and deployment loops.
Local + remote tools
Built native utilities, PWAs, and self-hosted gateways that connect personal devices, desktop tools, and cloud services into usable workflows.
Robotics + systems
Built and field-tested an autonomous mower prototype, with earlier work in exchanges, wallets, scanners, APIs, and deployment operations.
