Summary
🤩
RockstarTao Peng is a Staff Engineer at Ant Group with 25 years of experience specializing in Linux kernel, file system and network file system development. He is an active open-source contributor—working on projects like Nydus (the Dragonfly image service) and e2fsprogs—where his work has ranged from fixing GZIP decompression bugs to refining inode and blob cache logic. His background spans kernel storage internals, container runtimes and cloud storage integration (Frakti, runv, hyperd, Ceph RBD) as well as improving CI and test stability for Kata Containers. Based in Chengdu and keeping close ties to academic communities, he blends low-level systems craftsmanship with pragmatic engineering for production-scale platforms. He’s known for being hands-on and reachable on Slack as @bergwolf, often diving into subtle compression and caching issues that most engineers don’t touch.
