Hello, I'm
Zhang Qianqian
Senior AI Lead Software Engineer
AI Solutions Engineer & Product Builder
I turn business problems into AI-powered products that ship. Over the past 2 years, I've delivered 3 production CRM systems, processed 6,000+ leads through an AI sales pipeline, and built 10+ automation workflows across sales, finance, and consumer departments — all while managing a small team. With 14+ years of full-stack depth and a career that spans data science, product ownership, and engineering leadership, I bring the rare ability to own an AI solution end-to-end: from understanding the business need to deploying and supporting the product.
