About Me

Hiđź‘‹! I am a Ph.D. candidate at the Massivizing Computer Systems Group, supervised by Alexandru Iosup. I work at the intersection of computer systems and AI. My work focuses on building data pipelines and software tools that analyze large-scale and real-world operational data, especially around cloud systems and large language models.
