About Me

Christy Lee

Nice to meet you.

I'm Christy — a full-stack developer who loves building seamless experiences from frontend to backend.

I love turning ideas into real products, whether it’s building scalable backends or creating clean, intuitive interfaces. Lately, I’ve been exploring AI tools to make apps smarter and more efficient.

When I'm not coding,I'm usually listening to music and walking through the city or along trails.

Based in Toronto, Canada
