Core Project: Yunchigo (Full-Category E-Commerce Platform)

• Fintech & Payment Testing: Spearheaded all-link performance stress testing and monitoring for core transaction flows, payment gateways, and marketing campaigns during peak shopping festivals (e.g., Double 11).
• High-Concurrency Stress Testing: Built a distributed testing cluster using Locust, writing native Python scripts leveraging coroutines to simulate massive traffic peaks of up to 10W+ QPS.
• Bottleneck Localization: Monitored real-time system metrics during stress tests to pinpoint backend bottlenecks (e.g., Redis cache breakdown, slow SQL queries, database deadlocks) and collaborated with developers to optimize architecture.
• Data Factory Development: Authored Python automation scripts for data generation, batch-creating and cleansing vast amounts of product and user data for testing, reducing prep time by 70%.
