About Deepak Kumar

I am a technologist specializing in Machine Learning/AI and lead our Ads Marketplace efforts at LinkedIn. The Ads Marketplace area includes all algorithmic, product engineering and infrastructure efforts across retrieval and ranking, forecasting, bidding and pacing, and auction mechanism design. Between 2022 and 2024, I built out the Data and AI org at Handshake, and state-of-the-art ML algorithms and infrastructure to revolutionize the early career hiring marketplace. Previously, at LinkedIn, I built out and led world-class engineering teams focused on the marketplaces for Ads, Jobs, and Learning. My team and I were able to have a material impact on the business (e.g, M USD) through innovations in bidding algorithms, ad-density optimization, nearline/real-time personalization, etc. Prior to that, at Google, I developed core technologies to enhance the effectiveness of Google Ads. I helped answer fundamental questions like, “What is the incremental value of paid search? What kinds of advertisers benefit from having dedicated sales teams, etc.” I derive the greatest fulfillment from building and leading teams of world-class scientists and developers, steering them toward pioneering technological advancements and breakthrough product innovations.

   I lead the AI, AI infra and serving teams across the Ads Marketplace. This includes retrieval, ranking, and allocation (ie bidding, pacing, forecasting, auction design) efforts up and down the stack. We are currently modernizing our stack across the different pillars (retrieval, ranking, and allocation) by scaling training (data, compute, model size), inference, auction throughput, etc. while also overhauling our ad allocation algorithms to resemble a large scale bin packing problem.
