At Ant Group, I develop and optimize Alipay’s online advertising serving systems, focusing on latency, reliability, and production stability. The infrastructure handles 700,000+ QPS.
I designed and implemented a dynamic computation allocation framework for online serving, enabling adaptive resource scheduling under high traffic workloads.
I also improved serving reliability through architecture and failure-handling changes, raising the service success rate from 95% to 99% and contributing to a 2% increase in advertising revenue.
At ByteDance, I developed backend services for advertising media platforms and built a plugin management platform from 0 to 1. It enabled dynamic SDK plugin delivery and increased plugin coverage from 0% to 80%.
