Rockstar🎓
Top SchoolRafia Sabih is a Senior PostgreSQL Core Developer with 11 years of experience designing and optimizing high-performance relational databases, currently based in Berlin. She has driven measurable improvements in PostgreSQL parallelism and index scans at EnterpriseDB and deepened time-series query optimization while contributing to TimescaleDB’s core extension. At Zalando she bridged database engineering and Kubernetes operator work, adding standby cluster support and connection pooler features, demonstrating both backend and DevOps fluency. An active member of the PostgreSQL hackers community and frequent conference speaker, she combines rigorous benchmarking (TPC-H) with practical R&D to influence upstream Postgres features. Less obvious: she pairs low-level internals work with production-grade orchestration, making her effective at taking research ideas into resilient, deployable systems.
