Summary

Rockstar🎓
Top SchoolFeihong Qian is a Senior Software Engineer based in California with six years of experience designing and operating high-performance, highly available, and secure distributed back-end systems. He has built cloud-native recommendation platforms at ByteDance that serve global products like TikTok and Douyin, and previously scaled microservice ecosystems and Kubernetes infrastructure for IXL Learning supporting millions of users. His background includes leading teams to deliver data-intensive features—such as a Spark-based feedback analyzer and a distributed content fetcher—that measurably improved CTR and reduced datacenter costs. Trained at USC and NYU, he blends strong security-first engineering (anti-CSRF, DDOS mitigation) with a knack for platform-level automation and observability. Notably, he moves comfortably between algorithm-facing platform work and operational tooling, enabling both large-scale streaming/indexing workloads and smoother developer experience.
