Summary
🤩
Rockstar🎓
Top SchoolZiyang Guo is a software engineer and Yale mathematics student with eight years of technical experience bridging backend systems, databases, and finance. He has built core components of custom infrastructure—implementing a transaction manager, B+ tree storage, caching strategies, and a Netty-backed RPC framework with multi-serializer support—demonstrating deep systems and protocol-level skills uncommon for a junior. Complementing his engineering work, he has hands-on deal and analytics experience from internships at Tencent, Temasek, CICC, and a quantitative research stint at Ellington, making him fluent in both code and capital. Based in Hangzhou with roots across top Chinese and US institutions, he combines rigorous mathematical training (near-perfect GPAs) with practical product and service-discovery integrations (Nacos, Protobuf, Kryo). Colleagues would note his equal comfort diving into low-level performance optimizations and translating technical tradeoffs for finance stakeholders.
