Rockstar🎓
Top SchoolTony Hutter is a seasoned software developer with 11 years of experience building and maintaining low-level Linux systems, device drivers, and storage infrastructure from Livermore, California. He currently develops and maintains ZFS on Linux at Lawrence Livermore National Laboratory and contributes to high-performance storage and telemetry tooling such as Splunk, AXL, and UnifyFS. His background includes embedded Linux and FPGA bring-up, PCIe/I2C/SPI driver development, and custom ASIC interconnect work from roles at Cray and Hewlett-Packard. Tony combines systems programming in C and kernel internals with practical scripting and distro maintenance, making him comfortable across both hardware bring-up and production deployments. An active open-source contributor and OpenZFS maintainer, he has implemented feature-level improvements (zpool iostat histograms, autoreplace/error reporting) and keeps documentation current for broad user bases. Colleagues rely on his ability to translate schematic-level hardware details into robust kernel drivers and operational tooling.
