Top SchoolGary Kramlich is a senior system administrator and seasoned systems programmer with 21 years of experience building and operating large-scale Linux infrastructure and cloud-native platforms. Based in Milwaukee, he specializes in C development on UNIX/Linux, complemented by C++ and Python work, and has a long track record of shipping robust, well-tested code for projects like CuraEngine and the Kubernetes external-dns controller. He manages production fleets and Kubernetes clusters at scale—running Salt for 10,000+ machines and upgrading EKS clusters—while also leading the Pidgin open-source project, where he maintains infrastructure, mentors contributors, and builds reusable GTK and NAT traversal libraries. A largely self-taught coder who started at age 12, Gary blends deep low-level debugging skills with practical DevOps solutions (including Talos Linux test clusters and global fail2ban integrations) and frequently shares his work publicly via streaming and open repositories.

Contributions summary:Gary primarily focused on improving the build and output of the GCode engine. They addressed compiler warnings and ensured the code base was standardized by running dos2unix on gcodeExport.h. Further contributions involved altering the default output of GCodeExport to stderr and updating unit tests to check against the actual output of generated gcode files, thereby improving the reliability and testability of the CuraEngine's output. The user also made adjustments to the Makefile, and addressed potential NULL pointer dereferences within the model file loading process.
