Legina Chen is a Senior Software Engineer with seven years of experience building scalable back-end systems, currently designing multi-tenant distributed queuing infrastructure at Datadog. She has progressed through multiple engineering roles at Datadog after internships at Google and Facebook, bringing practical experience with FoundationDB, Redis HA, metadata stores, and blob storage. Her open-source contributions include meaningful back-end work on Google's Nomulus registry, where she implemented database entities, DAOs, and migration scripts for threat match data—demonstrating strong schema design and data migration skills. Legina combines production-grade engineering with a grounded academic background from UC Berkeley in Computer Science. Colleagues describe her as a pragmatic problem-solver who refactors and hardens systems rather than adding superficial features. She often tackles the gritty, non-glamorous parts of distributed systems that make large-scale services reliable.
