Summary
🤩
Rockstar🎓
Top SchoolRunzhou Zhang is a transport network engineer with seven years of experience designing and optimizing hyperscale data-center and cloud networking for Meta and AWS. He combines deep photonics and DSP research—authored work in Nature Photonics and >15 peer-reviewed publications—with hands-on engineering to improve topology reliability, capacity planning, and monitoring for large compute infrastructures. At AWS he focused on photonic/electronic interconnects and metrics for AI/ML-accelerated networking, and at Meta he now drives what-if risk analysis and global transport topology design. He also contributes to prominent open-source cloud tooling, enhancing AWS CDK Lambda and event-source integrations for DynamoDB, Kinesis, SQS and Kafka. Based in Seattle, Runzhou brings rare cross-domain fluency between academic photonics research and production-scale network engineering. He is particularly skilled at translating advanced physical-layer insights into measurable operational improvements for hyperscale systems.
