About

Currently working on YouTube's personalization infrastructure, the stack for serving petabytes of data at hundreds of millions of QPS powering YouTube recs, GenAI workflows and LLMs, and deep learning. I also work on the bleeding edge of an intersection between GenAI, reinforcement learning, Ads prediction + modeling, and deep neural nets. I work with partners across Alphabet - Shopping, Gemini, YouTube Ads, Search Ads, YouTube Organic in developing SOTA models for powering the next generation of content targeting across YouTube. I've built large-scale data and telemetry pipelines for Azure machine learning services. Prior to that I worked across teams to integrate Bing search index with an Azure app streaming service, enabling an in-browser experience. I have a background in distributed systems. I have worked with talented people on many teams, shipped projects, and am always on the lookout for interesting opportunities.
