John-Mark Gurney grew up programming computers. After learning C++, he
went looking for a free compiler and, in 1994, found FreeBSD. He became
a committer in 1997. As FreeBSD has expanded its platform support, he
worked on the sparc64 architecture and supported a new ARM SoC that
included a suite of device drivers. He has also done MP work, including
making kqueue MP-safe.
