More Than a Developer
I'm Yongjie Xie, a developer based in Waterloo, Canada. I build AI-powered applications and full-stack products with TypeScript, React and Python, bringing 10+ years of product-management experience to build applications that align business goals with technical execution.

With 10+ years in Product Management, I bring a unique dual perspective to Full-stack Development. Beyond coding, I specialize in strategy, architecture, and design. I independently own the full lifecycle—from concept to deployment—bridging the gap between engineering and business to balance UX with strategic goals.
