I received my master's degree in Computer Science from the Vienna University of Technology in May 2014. I wrote my master's thesis at the Complang Group (Institute of Computer Languages). During my studies, I have worked as a teaching assistant for the lectures Database Systems, Functional Programming, and Semistructured Data. In summer 2018 I was research intern at IBM Research in New York.
My current research focuses on Continuous Delivery/Deployment, Software Release Processes, and Continuous Experimentation. I'm interested in the techniques used for experimenting with new software features on a small fraction of the user base in production environments. This includes for example gradual releases (partial rollouts), A/B Testing, and dark launches. My work focuses on tooling to support developers and release engineers conducting such experiments in an automated and data-driven manner.
Responsible assistant for Software-Praktikum (SoPra) in 2015 and 2016, advising/consulting role in 2017 and 2018. Guest Lecturer in Advanced Software Engineering on Release Engineering in 2016, 2017, and 2018.
