Marc Mutz is a Principal Software with The Qt Company. Starting out around the turn of the century as a KMail/Kontact Core Developer, he has since wandered down the software stack to become a major contributor to the Qt Project, and maintainer of its QtWidgets module.

Having taught more than 25 multi-day Qt trainings to companies such as Schlumberger, EADS and Siemens, during his tenure at KDAB, he was also among the first batch of Qt developers certified by Nokia's now-defunct Qt certification programme in 2009.

Marc is writing -Wmarc, a blog about Qt, Boost and C++, but is recently enjoying his new role as parent and—increasingly less so—as a house builder.
