About Yuetian Lou

I build and lead platform engineering teams that ship reliable, high-throughput infrastructure at enterprise scale.At Qualtrics, I manage a team owning real-time streaming and data ingestion pipelines processing tens of billions of events per day — maintaining 99.9% availability and sub-300ms p99 latency. When our platform faced a critical scale incident with one of our largest customers, I flew to their headquarters, presented root cause analysis and a remediation roadmap to 20+ VP-level stakeholders, and helped secure a $5M, 3-year renewal. That\'s the kind of ownership I bring.I\'ve led a full platform re-architecture that delivered a 10x traffic capacity increase in a single quarter, onboarded 15+ enterprise customers without a single scale incident, and scaled the platform to absorb 200% user growth with no increase in hardware cost.On the people side: 100% promotion success rate across 7 engineers, 5 hires, and zero regrettable attrition. I care deeply about helping engineers grow and find roles where they can do their best work.Background: CS Master\'s from Ohio State, 6 years as an SDE (Expedia, Qualtrics) before moving into engineering management. I\'m deepening my ML infrastructure expertise and interested in opportunities at the intersection of distributed systems and ML platform engineering.
