Biography

I am a final-year PhD Candidate at the Systems Group at ETH Zurich, graduating in June 2026. My research focuses on distributed systems, cloud orchestration, resource management, and network systems. I am advised by Prof. Dr. Ana Klimovic and co-advised by Prof. Dr. Timothy Roscoe. I received my MSc and BSc degrees from the University of Belgrade, School of Electrical Engineering in Serbia.
