Summary
👤
Senior🎓
Top SchoolKiryl Shutsemau is a veteran software engineer with 26 years of hands-on expertise in Linux kernel internals, embedded systems, ARM platforms and virtualization, now working on kernel development at Meta. He spent over a decade at Intel driving TDX guest enablement, memory-management features (5-level paging, MTE, TME), and scalability improvements, and is an upstream maintainer with deep low-level systems experience. Kiryl is an active contributor to torvalds/linux—implementing x86 topology, MTRR/TDX/PAT changes and optimizations—and has improved cross-platform tooling like libgit2 through bug fixes and test automation. Comfortable across distributions, toolchains and device trees, he blends system architecture thinking with meticulous kernel hacking. Colleagues rely on him to shape architecture to fit Linux while keeping complex features maintainable and performant.
