In November 2025, Adrian Chadd contributed foundational FreeBSD build support to the google/perfetto repository, enabling core components to compile and run on FreeBSD systems. His work focused on cross-platform development and system programming in C++, addressing OS-level compatibility to establish a baseline for future tracing provider features. Adrian collaborated closely with the FreeBSD community to ensure alignment with platform expectations, co-authoring commits to integrate feedback. While no major bugs were fixed during this period, the depth of engineering established a robust starting point for broader Perfetto adoption on FreeBSD, demonstrating expertise in build systems and collaborative open-source development.
