When not working on smartmessages.net and supporting 1CRM, I’m the maintainer of PHPMailer, a top-10 PHP project on GitHub, and probably the world’s most popular email sending code. I’m a contributor to many other open-source projects, and I wrote the WHATWG HTML5 email address specification. I’m an accomplished Linux sysadmin and MySQL DBA, providing performance, scalability and security consulting, and I’m a technical writer and pentester for Radically Open Security. I’ve spoken at technical conferences in the UK, Spain, the Netherlands, Germany and the USA. I live in the French alps with my wife and kids, where I can indulge my passions for skiing and mountain biking.
