I’m a Researcher at Facebook AI Research working on machine learning for systems where I’m currently exploring reinforcement learning to improve the performance of computer networks. Prior to that, I was part of Facebook AI Applied Computer Vision Research group where I founded and lead the Rosetta project—a large-scale machine learning system for understanding text in images and videos. I had also made extensive improvements to the low-level performance and efficiency of Computer Vision models in production.   I spent my first few years at Facebook working on our distributed BLOB storage infrastructure, and then on the traffic infrastructure team working on Proxygen, our open-source reverse proxy. I was also one of the early infrastructure engineers on Facebook Live video-streaming which I helped scale.
