Summary
🤩
Rockstar🎓
Top SchoolFred Zhang is a Lead Software Engineer in San Francisco with 11 years of experience building scalable backend systems and developer-facing tools, currently driving Google’s Firebase + SQL Data Connect initiative. He grew an interdisciplinary team from zero to 20 engineers and shipped a GraphQL-to-SQL compiler, public preview Data Connect with native vector search, and integrations that bridge Firebase and Cloud SQL. Fred combines deep distributed-systems experience (RTDB traffic management, Paxos migrations, multi-region rollouts) with hands-on contributions to prominent open-source Firebase repos like firebase-tools and firebase-js-sdk. He’s equally comfortable designing high-level architecture and refactoring core SDKs and queues, and has applied ML-driven evaluation techniques to power the Data Connect Gemini model. An educator at heart, he started as a teaching assistant and maintains a practical curiosity for tooling and systems.
