Summary
👤
Senior🎓
Top SchoolBreno Leitao is a seasoned kernel engineer based in London with 11 years of deep systems and low-level Linux experience, currently working on Meta’s kernel team. He has a strong track record in device drivers, embedded platforms, virtualization (QEMU/KVM/libvirt) and large-scale VM deployments, and is routinely hands-on with firmware and kernel internals. An active open-source maintainer and committer (Debian ppc64el port maintainer, FreeBSD committer, Alpine and Linux kernel contributor), he has contributed to high-profile projects including the mainline Linux tree and NVMe tooling. His work blends performance analysis, OS development and platform bootstrap efforts—an unusual mix that has seen him add architecture support across distributions and optimize I/O and networking subsystems. He pairs academic training in operating systems with practical production-scale reliability improvements at companies like IBM and Meta.
