Senior Software Engineer @ Google · Machine Learning · Recommender Systems
Hello! I'm a Senior Software Engineer at Google, working on the Google Play Store Personalization team — using machine learning to help billions of Android users discover their next favorite app or game.
The road here was a bit winding: six summers as a New Jersey ocean lifeguard (my Baywatch career), an undergrad in Game Design at RIT (where, on top of my academics, I wrestled four years for the NCAA D3 program and was team captain), software engineering internships across frontend, backend, and data engineering roles at eHealth Technologies, GeekHive, Enigma Technologies, and Bluecore, and a Masters in CS at NYU focused on Machine Learning and AI.
Outside of work I'm into reading, fitness, travelling, photography, and being a dad.
Current Work
A series of state-of-the-art two-tower neural recommenders built with PyTorch. Each model learns separate user and item embeddings from interaction history and content features, trained with full softmax and Menon popularity debiasing so results reflect genuine taste — not just what's trending. No account needed.
