Top SchoolDaan De Meyer is a founding engineer and systems-focused software developer with 11 years of experience building and productionizing low-level Linux infrastructure and networking tools. A Hasselt University computer science master's graduate, he currently contributes upstream to systemd as part of Meta’s Linux Kernel team and maintains systemd/mkosi while authoring the cross-platform reproc C/C++ process library. His work spans kernel-adjacent services, build and test automation (notably contributions to Meson, CMake and doctest), and performance improvements that turned slow CLI workflows into production services at Meta. As a side accomplishment from his thesis he achieved the first end-to-end Facebook page load over QUIC/HTTP3 in Chrome, reflecting a deep interest in networking and protocol-level performance. Based in Belgium, he combines pragmatic DevOps and backend engineering with sustained open-source stewardship across widely used projects.
