Hi - I'm Junyuan, an AI automation engineer and front-end developer. I build production-ready AI pipelines and the interfaces that deliver them.

WHAT I DO

- AI agent systems: multi-agent orchestration with Coze / Dify / LangChain / AutoGen, including task routing, retry and fallback logic, and quality scoring.

- AIGC content pipelines: Stable Diffusion / ComfyUI workflows, LoRA fine-tuning, ControlNet and IP-Adapter for consistent characters, plus Runway / Pika video.

- Custom web front-ends: semantic HTML5 + modern CSS (Grid/Flex, CSS variables, clamp), no heavy framework, Lighthouse 95+ and WCAG AA.

- Integrations and automation: REST APIs, webhooks, Telegram / Feishu bots, Python / FastAPI services, Docker deployment.

HOW I WORK

Day 3: first working version you can click through. Day 5: final delivery.

You get full source code, cross-browser testing, and a plain-language guide so your team can update content without me.

I take fixed-price or hourly work and I am comfortable with escrow milestones. Send me your goal in one or two sentences and I will reply with a concrete plan, timeline and price.
