Paul Yang is a software engineer with 11 years of experience building large-scale data infrastructure and distributed systems, currently contributing to MetricFlow at dbt Labs. He has a strong track record at major tech firms—Facebook, Instagram, Airbnb—where he led projects spanning petabyte-scale HDFS migrations, incremental replication for Hive, Airflow scalability, and storage/scheduling/security for data platforms. As a former co-founder at Transform, he pairs hands-on back-end engineering with product and hiring experience for data and infrastructure teams. His open-source contributions include CLI and UX-focused improvements to MetricFlow, reflecting an emphasis on making metric computation and configuration more user-friendly. Trained at MIT in EECS, he brings deep systems-level expertise combined with practical operational experience in multi-datacenter and compliance-sensitive environments. An underappreciated strength is his history of bridging low-level system design (storage, schedulers, replication) with developer-facing tooling that improves day-to-day productivity.
