Inside Walmart: Tianyu Zhang on How AI Is Changing Software Engineering
Walmart engineer Tianyu Zhang shares how AI tools evolved from buggy assistants into powerful collaborators embedded in daily development workflows.
Tianyu Zhang, a software engineer at Walmart, has witnessed the gradual transformation of AI in the workplace over three stages of her career. Initially, AI tools were experimental and provided little assistance to engineers in building production-ready code. As AI capabilities matured, Zhang observed a shift towards practical engineering collaboration.
In her second role, she worked on developing AI-powered inventory and shelf-recognition tools, noting that AI coding tools were still buggy and unstable during this period. Despite the challenges, Walmart offered internal learning opportunities and AI coding tool knowledge sharing sessions. By the end of her second role, AI started to become an integral part of engineers' workflows.
While AI could generate cleaner and more structured code, contextual reasoning remained a challenge. However, AI proved valuable in areas such as code reviews, documentation, and unit testing.
