Summary
🤩
Rockstar🎓
Top SchoolIsabella Siu is a Senior Software Engineer based in New York with 12 years of full-stack and backend experience, now building observability at Grafana Labs. She brings deep systems and database expertise from several years contributing to MongoDB drivers in both Go and C++, where she improved bulk write/indexing behavior, reduced allocation overhead, and added features used broadly across the driver ecosystem. At Grafana she has focused on robust datasource integrations for Google Cloud Monitoring and Azure Monitor, migrating logic to backend services and modernizing authentication flows. Her work shows a pattern of stabilizing core libraries and specifications—designing APIs, improving observability, and hardening background monitoring in production systems. Isabella combines production-grade engineering with open-source collaboration, having changes that impact thousands of downstream projects and developer workflows. She holds MS and BS degrees in Computer Science from Rensselaer and often mixes low-level performance optimization with pragmatic, user-facing API design.
