Rockstar🎓
Top SchoolStefan Hundhammer is a seasoned Linux systems developer and architect with 25 years of experience building robust C++/Qt applications, low-level Unix system software, and systems-management tools (notably YaST at SUSE). He specializes in embedded and desktop Linux, GUI (X11/Qt) development, cross-platform C++ libraries with strong binary-compatibility discipline, and practical API and usability design. Stefan combines system-level expertise (syscall-level coding, storage, RFID, barcode tech) with distributed back-end work (GearMan/JSON), and has a track record of creating frameworks and build systems that simplify long-lived projects. He leads and mentors engineers, teaches Qt/C++/Linux, and has maintained notable open-source projects—original author of KDirStat and current lead on QDirStat, where he implemented advanced process-output handling and multi-process UI features. Based in Bavaria (Marktschorgast/CET) he is selective about opportunities and prefers local engagements around Nürnberg or Bayreuth, reflecting a pragmatic focus on productive, timezone-aligned collaboration.

Contributions summary:Stefan implemented and integrated the `ProcessOutput` class, demonstrating a focus on managing and displaying the output of external processes within the `qdirstat` application. This involved creating a terminal-like window, handling different output streams (stdout and stderr), and managing multiple processes concurrently. The changes also included adding functionality for auto-closing the window and enabling options to control the display behavior.
