Summary
👤
Senior🎓
Top SchoolPetr Machata is a Staff Software Engineer with 20 years of systems and networking experience, focused on GNU/Linux toolchains, debuggers, TCP/IP and the Linux kernel networking subsystem. He has deep hands-on expertise driving open-source kernel drivers for datacenter switches at NVIDIA and Mellanox, including tunneling offloads, QoS, ERSPAN and PTP support. An active contributor to high-profile projects like iproute2, linuxptp and the Linux kernel self-tests, he has extended core networking tooling and improved test reliability and automation. Comfortable in C and low-level systems work, he also bridges user-space and kernel-space concerns, refactoring libraries (libnetlink/libmnl) to enable batch processing and more flexible attribute handling. Based in Prague, he combines production-grade engineering with a packager’s attention to portability and cross-architecture correctness from his Red Hat background.
