Senior🎓
Top SchoolDarrick Wong is a seasoned kernel hacker with 13+ years designing and implementing Linux storage and filesystem features, currently driving filesystem integrity and self-repair work at Oracle. He has shipped major enhancements to XFS and ext4—metadata checksumming, online fsck, integrity scanning, reflink/dedupe/COW, and block reverse-mapping—grounded in deep low-level expertise and fuzz-driven bug discovery. Earlier roles at IBM and Sun involved x86 bringup, storage drivers, energy optimization, and ext4 corruption detection, giving him broad systems-level perspective. An active contributor to flagship tools like e2fsprogs, he focuses on performance, robustness, and practical repair mechanisms for real-world deployments. Based in Beaverton, Oregon, he pairs rigorous technical problem-solving with a collaborative style that negotiates diverse stakeholder needs. Outside engineering he studies geology and pursues outdoor and performing-arts interests, which inform his patient, observational approach to complex debugging.
