Haochang Yang

Software engineer specializing in AI/ML and full-stack web development. I build production-ready, AI-powered applications end to end — from backend services and data pipelines to intuitive front-end interfaces — and integrate LLMs and AI agents into real products people use.My recent work includes RAG and agentic AI systems (LangChain, LangGraph, CrewAI), LLM tool integrations via the Model Context Protocol (MCP), and deep learning research in PyTorch. On the full-stack side, I’ve built and deployed applications with Python backends, React/TypeScript front-ends, PostgreSQL, and cloud-native deployment (Docker, CI/CD, AWS), with a focus on clean, scalable, maintainable code.I hold an MEng in Electrical & Computer Engineering from the University of Toronto, work independently and communicate clearly, and enjoy turning complex concepts into user-friendly products.
