Xin Zhang is a senior software engineer with 10 years of experience building high-throughput, production-grade backend systems across Yahoo, Amazon, and Meta. He has led large-scale integrations—most recently architecting a TikTok-facing backend that processes 600k daily queries with Sherpa KV stores and parallelized APIs under strict QPS limits—while driving cloud migrations and modernizing legacy C++ code for AWS. At Amazon he scaled marketplace features globally, cutting offline ingestion from 14 hours to 30 minutes and founding operational practices for new teams; at Meta he built an Interview Home platform that sharply improved reviewer throughput and product quality. Xin combines strong systems engineering with pragmatic product sense, routinely collaborating with PMs and data teams to boost engagement and reduce query reformulation. He holds advanced CS training from Carnegie Mellon and Tsinghua and brings a track record of measurable impact during peak events like the Olympics and elections. Notably, he pairs hands-on data-pipeline engineering (Spark, Oozie, KV stores) with practical on-call and team-building experience.
