Senior🎓
Top SchoolSeed Zeng is a Senior Staff Software Engineer in Greater Boston with 10 years of experience building high-throughput, fault-tolerant distributed systems for companies like DoorDash, Meta, and Klaviyo. He has repeatedly redesigned ingestion and streaming pipelines—most notably leading Abacus at Klaviyo to process billions of events and improve throughput by orders of magnitude—and has led services to detect inconsistencies across large-scale backends. A hands-on tech lead and mentor, he blends deep systems engineering (Kafka, Flink, Cassandra, DynamoDB) with practical migration and scalability work that turns prototypes into production-grade, horizontally scalable platforms. Academically strong with dual summa cum laude degrees in Computer Science and Physics, he pairs rigorous problem-solving with a penchant for performance optimization; his GitHub motto, “To strive, to seek, to find, and not to yield,” captures his persistent drive to push systems to their limits.
