profile

I’m a researcher working at the intersection of machine learning and software engineering. I currently work as a staff software engineer in Google’s DevAI team, where we build machine learning systems to make Google developers more productive.

Previously, I was a senior researcher on the PROSE team at Microsoft, where I worked on developing state-of-the-art program synthesis technologies to make software development more accessible, productive, and fun.

I received a PhD in Computer Science (CS) from MIT under the supervision of Martin Rinard, an MS in CS from NYU working with Dennis Shasha, and a BA in Economics from University of Pennsylvania. I’m originally from Costa Rica.
