Summary

Rockstar🎓
Top SchoolEvelyn Liu is a Senior Software Engineer in Palo Alto with 10 years of experience building high-performance distributed systems and cloud-native infrastructure. At Uber she designed and implemented Kraken, a peer-to-peer blob distribution service, and significantly sped up and shrank Docker image builds through contributions to Makisu, improving build times by 40% and reducing sizes by 50%. Proficient in Golang and Python, she blends backend engineering with DevOps practices—Docker, Mesos, Kubernetes, Nginx and ZooKeeper—to deliver resilient service workflows and cross-region replication improvements. Her work often targets real-world scale problems, for example multiplying replication efficiency tenfold and enabling safe decommissioning of over 1,000 services. Evelyn’s background from UCLA and hands-on open-source contributions reflect a pragmatic engineer who prefers measurable impact over theoretical design.
