Rockstar🎓
Top SchoolHaikuo Liu is a Senior Software Engineer in Sunnyvale with nine years building cloud-native infrastructure at top-tier companies including Uber, Google (Cloud Spanner), and multiple teams at AWS working on ECS and Fargate. He combines strong academic foundations—a CS master’s from Columbia and a high-performing undergraduate degree—with hands-on systems work in Go, debugging and extending Amazon’s widely used ECS agent to surface container metadata and make runtime behavior configurable. Comfortable in distributed systems and backend services, he has a track record of shipping pragmatic fixes and observability improvements that reduce operational friction. At Uber he continues to apply that expertise to large-scale production systems, blending deep implementation skills with an eye for developer experience. An unusual strength is moving quickly from debugging test-level issues to adding metadata and configurability that improve both testing fidelity and production troubleshooting.
