Lee Zhou

I’m a Full-Stack Web & AI Developer based in Canada, with hands-on experience building production-ready web applications, automation workflows, and AI-powered systems for real business use cases.

I specialize in modern web development (Next.js, React, Supabase) and AI integrations (LangChain, LangGraph, OpenAI), helping clients turn ideas into scalable, reliable products. I’ve built full systems end-to-end — from database design and backend logic to clean, responsive front-end interfaces.

My recent work includes:

• Developing AI agents capable of answering semantic, ranking, and time-sensitive queries using vector databases

• Building full-stack platforms (authentication, payments, dashboards, admin tools)

• Automating data workflows using n8n to reduce manual work and improve efficiency

• Designing databases and APIs with performance, scalability, and maintainability in mind

I’ve worked as a Python Engineer, Full-Stack Developer, and AI Developer, and I also bring a strong analytical background from my experience as a Financial Analyst — meaning I focus not just on code, but on business value and clarity.

What I can help you with:

• Custom websites & web apps (Next.js / React)

• Backend & database design (Supabase, PostgreSQL)

• AI chatbots, agents, and workflow automation

• API integration & system optimization

• MVPs for startups and small businesses

I value clear communication, clean code, and practical solutions. If you’re a local business or individual looking for a dependable developer who understands both technology and real-world needs, I’d be happy to help.
