Summary
Run Zhou is a Senior Software Engineer based in San Jose with a track record of designing resilient backend services and automation tools that materially reduce operational and testing time. At PayPal he delivered NLP-driven bug recommendation, distributed test execution, monitoring platforms and batch pipelines that cut testing from 100 to 30 minutes, improved reconciliation efficiency by over 90%, and helped avoid multi-million dollar losses. He mentors engineers, has led global incident response teams, and builds full-stack solutions combining Python Flask, Spring Batch, React, Teradata and Airflow to solve compliance and AML challenges. Now at Walmart Global Tech, he continues to apply pragmatic system design and observability to high-impact domains.
