Summary
🤩
RockstarRuohang Feng is a founder and PostgreSQL specialist with 11 years of experience building high-scale database infrastructure and developer-focused distributions. As the solo creator of Pigsty (a free, local-first PostgreSQL distribution and RDS alternative) he blends deep DBA expertise with DevOps and infrastructure engineering, having previously operated 40 clusters and 250 nodes supporting 2M TPS at Tantan. His background spans backend architecture and data warehouse design at Apple and product-level full‑stack and data platform work at Alibaba, so he moves comfortably between low-level DB tuning and product-driven system design. An active open-source maintainer (pgsty/pigsty) and documentation contributor, he focuses on distribution tooling, config automation, and operational reproducibility—skills that make him a modern “Postgres hacker” and distribution maker. Based in Shanghai and Singapore, he combines entrepreneurial grit with hands-on technical ownership, often shipping production-ready tooling solo.
