I am a 3rd year PhD student at the Department of Computer Science at the University of Chicago. I got my bachelor degree in Computer Engineering from the University of Santiago of Chile (Universidad de Santiago de Chile), Santiago, Chile, in 2012. Currently, im happily working at the University of Chicago with Professor Haryadi S. Gunawi as a research assistant.

My main research interests are related to Distributed Systems and Cloud Computing, focused on achieving more dependability in aspects like scalability and performance stability. In my vision, empowering developers and democratizing testing is a key factor in both advancing the state of the art of our field and speeding up the process of rolling out new software.
