Rockstar🎓
Top SchoolOmar Sandoval is a seasoned software engineer with 13 years of experience focused on Linux, filesystems, storage, and debugging, currently on Meta’s Linux kernel team in Seattle. He has designed and implemented kernel features including work on Btrfs and the Kyber multiqueue I/O scheduler, and is the creator of the drgn programmable debugger. An active open-source contributor, Omar improves critical projects such as Python's typeshed, fio, and upstream Linux, often tackling type-safety, refactoring, and tricky logging/CLI bugs. His background spans production storage systems at Isilon and infrastructure work at Dropbox, plus an early internship that scaled Btrfs free-space caching at Facebook. Colleagues know him for combining deep systems expertise with practical documentation and tooling improvements that make low-level systems more maintainable. He holds a BS in Computer Engineering from the University of Washington and routinely bridges kernel-level engineering with developer-facing tooling.
