Top SchoolBilly Liu is a Senior Software Engineer based in Seattle with 9 years of experience building full-stack applications and large-scale distributed systems for retail and analytics teams at Walmart, Amazon, and Nordstrom. He has led design and implementation of performance- and cost-focused solutions—streaming infrastructures with Kafka, React/TypeScript apps that reduced AWS spending, and recommendation systems for Amazon Fashion. Comfortable across backend (Java, Python, Django), frontend (React, Angular), and cloud-native tooling (Kubernetes, Docker, GitLab CI/CD), he blends product-facing delivery with infrastructure reliability. At Nordstrom he owned cross-functional design reviews and mentored interns, and at Walmart he’s now applying agentic AI to customer care—showing a move from data pipelines to intelligent automation. Collected from a co-op CS background at UBC, his work consistently emphasizes measurable impact like faster incident response and lower storage costs.
