About Me
Hey there, I’m Zheng Nian
I’m an AI & Full-Stack Engineer based in Beijing with 17 years of experience building scalable web applications and AI-powered solutions. I’m passionate about leveraging cutting-edge technologies to solve complex problems and optimize development workflows.
What I Do
Currently, I’m collaborating with Zhejiang University School of Management on the SunWu AI project (sunwu.ai), where I focus on developing an intelligent decision-making system using LangGraph and Deep Agents. This AI-powered system leverages multi-agent architectures to enable autonomous planning, reasoning, and decision execution for complex business scenarios. Before that, I spent nearly 6 years at Merico Inc., where I led the development of AI-powered developer tools that helped over 200 enterprises improve their R&D efficiency.
My expertise spans across:
- AI & Multi-Agent Systems: Building sophisticated multi-agent architectures with LangGraph and Deep Agents, specializing in intelligent decision-making systems, autonomous planning and reasoning workflows, and agent collaboration mechanisms
- AI & Data Engineering: Designing intelligent systems with LangChain, RAG architectures, vector databases, and state-of-the-art LLM integration
- Full-Stack Development: Creating robust web applications using React, Next.js, Node.js, and Python
- Backend Systems: Architecting high-concurrency APIs and IoT platforms that handle millions of requests
- DevOps: Implementing CI/CD pipelines, containerization, and cloud infrastructure
Notable Projects
SunWu AI - Intelligent Decision-Making System
Collaborating with Zhejiang University School of Management since April 2025 to develop an advanced intelligent decision-making system powered by multi-agent architecture. Built sophisticated agent workflows using LangGraph and Deep Agents, enabling autonomous planning, complex reasoning, and automated decision execution for business scenarios. The system demonstrates cutting-edge applications of agentic AI in strategic decision support and business intelligence.
DevChat - AI Programming Assistant
Led the full-stack development of an AI copilot tool that integrated multiple LLMs to automate code completion, reviews, and security scanning. The platform achieved 60,000+ code completions and identified 8,000+ security risks across 1.3 million files.
DevInsights - R&D Metrics Platform
Built a comprehensive data pipeline connecting 10+ development tools, aggregating 50M+ data points to provide actionable insights. The platform was adopted by 200+ enterprises and recognized as “Forbes Asia 100 to Watch.”
IoT Platforms
Architected Node.js-based IoT platforms handling 10M+ concurrent device connections, deployed across smart city and retail sectors.
Tech Stack
I work with a wide range of technologies including:
Languages: JavaScript/TypeScript, Python, Java, SQL, Dart, C, C#
Frontend: React, Next.js, Tailwind CSS, MobX, Flutter, Tauri
Backend: Node.js, Express.js, FastAPI, Spring MVC
AI/ML: LangGraph, Deep Agents, LangChain, OpenAI, Claude, RAG, Chroma, Qdrant, Multi-Agent Systems
Data: Airflow, dbt, PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ
DevOps: Docker, Kubernetes, Jenkins, GitLab CI/CD, AWS/Aliyun
Certifications
PMP (Project Management Professional) & ACP (Agile Certified Practitioner)
Beyond Code
I’m a strong believer in Agile methodologies and have successfully led cross-functional teams with a 98% on-time delivery rate. I also enjoy contributing to open-source projects - one of my projects, Apache DevLake, has garnered 2.7k+ GitHub stars.
