About Hu

Hu C.Status: Offline
Full Stack Developer | 13 Years | Next.js + Java | AI & RAG
Huanggang, China - 11:49 pm local time
Hi, I'm a full-stack developer with 13 years of experience. I build complete web applications from frontend to backend.

My recent focus is on AI-powered SaaS products. I build RAG-based chatbots that connect LLMs with your own data — not just API calls, but real knowledge systems.

What I can build for you:

AI chatbot with RAG (DeepSeek, OpenAI, vector search)
Full stack SaaS (Next.js + Java Spring Boot)
REST API and microservices architecture
Dashboard and admin systems
Tech stack: Frontend: Next.js, React, TypeScript, Tailwind CSS Backend: Java Spring Boot/Cloud, RabbitMQ AI: RAG, Prompt Engineering, Vector Search Database: MySQL, PostgreSQL, MongoDB, Redis, Elasticsearch

How I work:

I deliver working code, not just talk
Daily updates on progress
I ask questions early to avoid rework
Portfolio projects:

AI Mental Health Assistant — full stack SaaS with RAG, multi-theme chatbot
RBAC Management System — role-based access control platform
Let's talk about your project.
