Senior Staff Software Engineer at Crunchbase
San Francisco, California, United States
Summary
👤
SeniorGuangwen Zhou is a Senior Staff Software Engineer in San Francisco with 13 years of experience designing high‑stakes, revenue-critical back-end systems using Functional Programming and Domain-Driven Design. At Crunchbase he led a ground-up rewrite of the Billing Service from legacy Rails, delivered with rigorous testing and zero revenue impact, and built shared systems like a flexible, low-overhead Metering Service. He also reworked entitlement computation to calculate permissions at runtime, cutting 95th‑percentile session API latency from ~20ms to under 8ms at 20M daily calls. A pragmatic thinker and quick learner, he treats programming like LEGO—composing pure functions and separating description from execution—and insists on 100% business-logic test coverage. His background in English literature contributes to clear domain modeling and precise API contracts that reduce ambiguity in complex product logic.
