About Me

Since April 2022 I am working as a PhD student at the Chair of Software and Systems Engineering (Prof. Dr. Pretschner).

My area of research is integration testing of microservice systems. Integration testing is a crucial part of the development of software systems, as it specifically tests the interactions and interfaces between individual software components or services. Especially in the context of microservice architectures, the relevance of integration testing increases.

Prior to joining the chair, I completed my Master’s degree in Software Engineering, in an elite graduate program hosted by TU Munich in cooperation with the Ludwig-Maximilians University Munich and the University of Augsburg.
