Senior🎓
Top SchoolYuzhang Hu is a Staff Software Engineer based in Sunnyvale with 14 years of experience building high-throughput, low-latency ad serving and AI infrastructure systems at LinkedIn, Amazon, and Yahoo. He led DSP serving teams at Yahoo that scaled throughput from 2M to 5M QPS within a 100ms SLA and delivered $1M/year cost savings through low-level container optimizations. At Amazon and LinkedIn he shifted focus to industry-leading AI infrastructure and pricing/ads projects, bridging partner teams with production-ready tooling. Comfortable across backend, RTB pipelines, and performance tuning, he combines deep systems-level expertise with cross-functional collaboration across UI, API, data, and science teams. He publishes technical writing on his blog and maintains an active GitHub (finaldie), reflecting a habit of turning hands-on engineering into sharable knowledge. Not obvious from titles: he repeatedly champions cost-aware, low-level optimizations that materially reduce operating expense while improving service SLAs.
