Kefu Chai is a software developer with nine years of experience specializing in distributed storage systems, modern C++ and Python, and a strong track record as a maintainer and code reviewer. He spent years as a principal engineer on Ceph at Red Hat and later held senior architecture and engineering roles at XSKY and ScyllaDB, shaping large-scale storage architectures and core components. Now at Proxmox, he continues to focus on reliable, high-performance storage and infrastructure software. Kefu is an advocate for clear communication and pragmatic design, often bridging deep systems expertise with maintainability and developer ergonomics. Based in Shanghai, he blends an academic background in AI with hands-on systems engineering dating back to early work at VMware, EMC and Morgan Stanley—an uncommon combination that helps him reason about both low-level performance and system-wide behavior.
