Development of OpenStack networking infrastructure, in particular in conjunction with www.projectcalico.org
Neil has been hacking on free software since the early 1990s, with contributions including to Emacs, Guile, Lilypond, QtMoko, the GTA04 phone project, oFono, FSO, OpenStack, Dnsmasq, Linux and Dasher. He's also worked for 20 years for Metaswitch (previously Data Connection) in the world of networking protocols, and happily those two strands of experience are now converged in Project Calico, an open source implementation of simple and massively scalable data center networking.
