Summary
👤
Senior🎓
Top SchoolYijun Liu is a Software Engineer III with nine years of experience building scalable, production-ready back-end systems, currently focused on Web3 infrastructure at CertiK. He designed and implemented near real-time blockchain data ingestion and normalization pipelines across Bitcoin, EVM chains and Tron, and led the SkyNode validator deployment effort to ensure high availability and secure node operations. Skilled in Python, Go, Kafka and distributed datastores (TiDB, Redis, PostgreSQL), he combines systems programming with operational rigor to deliver low-latency analytics and robust monitoring. With dual master's training—computer science and naval architecture—he brings a methodical, engineering-first approach to complex distributed systems. Colleagues know him for quietly tackling hard reliability problems ("speak softly and carry a big stick") and bridging infrastructure, product, and ops to keep critical blockchain services running.
