I'm a Software Engineer at Cloudera. I completed a Ph.D in Computer Science at the University of Chicago under Prof. Haryadi Gunawi in UCARE group. I got my bachelor degree in Computer Science from Universitas Gadjah Mada, Yogyakarta, Indonesia, in 2011.

I am interested in Distributed Systems, Cloud Computing, Performance, and Reliability.
