Lotz is a software developer who is at home in many programming languages and on very different platforms. His expertise extends from programming applications by way of embedded software engineering and controlling installations to networks.

Lotz discovered his passion for programming when he was nine and he taught himself the basics using a handbook and an English dictionary. He completed an apprenticeship as computer programmer and worked freelance for many years before joining iart in 2010.

In his free time, Lotz works more or less intensely on Haiku, an open-source project that is building and developing an operating system modeled on BeOS, and he is also interested in everything that can be controlled by a computer: 3D printers, CNC milling, robotics, and so on.
