I am a software engineer at Facebook where I work on large scale sparse models for personalization. I co-authored a system capable of training and serving models with tens of billion parameters that is powering Ads and Feed Ranking. Later I was one of the core developers of Caffe2 framework that brings power of neural nets to multiple areas at Facebook.
Before Facebook I graduated with MS in Applied Mathematics in Ukraine. While in college I had a successful career in programming competitions and was ranked in Top 20 on Topcoder.
