Marcus Bointon is a seasoned pentester, code auditor and CTO with 17+ years building and operating high-throughput, distributed web systems — notably architecting Smartmessages.net which handles up to two million emails a day. He’s the long-time maintainer of PHPMailer (a top-10 PHP GitHub project used on tens of millions of sites), an active open-source contributor across backend and frontend projects, and a regular international conference speaker on PHP, email, security and privacy. Marcus blends deep Linux sysadmin, DevOps and backend expertise (PHP, MySQL, nginx, TLS) with practical privacy and GDPR consulting, and has run pentests, code audits and load tests for security firms. He also brings rare multimedia roots from the 1990s—shipping over a million CD-ROMs and running training programs—so he’s comfortable bridging creative and technical teams. Based in Auvergne-Rhône-Alpes and working remotely since 1995, he’s equally at home improving image and mail libraries as he is architecting resilient production services.
