Senior Staff Software Engineer

I grew the Feature Platform to serve all of LinkedIn's major ML applications including Search, Feed, Ads, and Jobs, together with the amazing 20+ person team I led. In partnership with Microsoft Azure, we released the open-source version named Feathr, a Linux Foundation AI & Data project with 1.9k stars on GitHub, and deployed it for dozens of companies across industries. I also served as a tech lead for other parts of LinkedIn's AI Platform, especially the model training pipeline. My specialty is using deep understanding to turn hard migrations into easy migrations, speeding the rollout of advanced new capabilities. I also have a passion for helping new leaders grow.Most recently, led the strategy for supporting large graph models (GNNs) in LinkedIn's AI Platform. Think Kumo.ai, but tailored for LinkedIn's scale and businesses.

Frame), the novel feature platform that simplified ML development at LinkedIn, reducing feature engineering task time from weeks to days, doubling feature data preparation runtime performance compared to legacy solutions, while reducing code burden. My system was voted by LinkedIn's ML engineers as top innovation for improving ML productivity compared to several competing proposals. Led small seed team to build and deploy (I was top code contributor). Won 1st Place Distinguished Contribution Award at MLADS conference. Numerous patents filed.Previously, served as tech lead of LinkedIn's Recommender Engine powering several LinkedIn products. Optimized performance, added cutting edge new ML modeling capabilities, and co-authored a KDD paper with users about innovative applications of the recommender stack.Before that, led the development of a Real-time Activity Stats platform. Turned a small project into a critical component serving real-time features for several major ML applications across LinkedIn.
