I work at KDAB as a Software Engineer and contribute to KDE for quite some years now. I am one of the most active contributors to KDevelop and Kate. Tooling in general is of huge interest to me, I wrote the Massif-Visualizer and more recently heaptrack to aid developers in improving the memory consumption of their applications. Additionally, I started to contribute to Linux perf. At KDAB I also worked on GammaRay which is invaluable to any Qt developer. Recently, I also started training developers in the art of debugging and profiling software with various tools.
