 **Cliff Green** (cliffg at connectivecpp dot com) is a software engineer and has worked for many years writing infrastructure libraries and applications for use in networked and distributed systems, typically where high reliability or uptime is required. The domains where he has worked include wireless networks (in particular cellular 9-1-1), location technology, and large scale embedded and simulation systems in the military aerospace industry. He has volunteered many years at [CppCon](https://cppcon.org/) (when it was in Bellevue) and presented at BoostCon (before it was renamed to [C++ Now](http://cppnow.org/)).
