BiographyI am a first-year Ph.D. student at Czech Technical University in Prague at the Department of Geomatics. Since summer 2020, I am a part of the GRASS software development community. On the basis of two participations in the Google Summer of Code (GSoC) program, I helped to improve the software's user interface and design a new prototype of a Single-Window user mode. In October 2021, I had a talk at FOSS4G with the contribution "I hated the way GRASS started so I changed it". In addition to the development of the GRASS GUI, I am involved in the development of a new Czech cadastral publication database in connection with the use of vector tiles, which is also related to the topic of my dissertation.
