Summary
🤩
Rockstar🎓
Top SchoolMario Limonciello is a Principal Member of Technical Staff with 17 years of experience building low-level systems, firmware update infrastructure, and hardware-facing software across industry leaders like AMD and Dell. Based in Austin, he combines deep electrical engineering roots with production Linux kernel and firmware work—contributing to high-profile projects including the Linux kernel and fwupd, where he improved firmware plugins, CI, and hardware safety modes. At Dell he led Linux firmware update stacks and vendor relationships; at AMD he continues to shape power, display, and CPU frequency subsystems for modern hardware. He’s equally comfortable in back-end and DevOps roles, automating test frameworks, Dockerfile generation, and cross-platform CI for Debian, Ubuntu, and Windows. Colleagues rely on him to bridge firmware, kernel, and user-space concerns, turning complex hardware behaviors into reliable update and power-management flows. An electrical engineering graduate from Iowa State, he brings uncommon breadth—from Verilog and analog lab automation to kernel-level patches—helping hardware features land cleanly in open-source ecosystems.
