I am a skilled and experienced software tester and application developer with a background in research and teaching. I hold a Doctor of Philosophy degree in Data Structure and Software Dependability from Brandenburgische Technische Universität Cottbus-Senftenberg, where I developed algorithms and methods for the modeling and simulating tool Snoopy - A well-known Tool for Petri nets). I also extended colored and plain quantitative Petri nets to model uncertainty in kinetic parameters. I have worked as a software tester for Philotech, where I developed unit tests, conducted requirement engineering, and performed agile software testing for the automotive industry.
