About

Senior Data Scientist at American Express

I build foundation models, recommendation systems, and GenAI applications on large-scale transactional data, with work spanning fraud, risk, and marketing.

I write to turn papers and implementations into practical explanations, from vector search and cryptography to prompt optimization and production machine learning. Outside work, you will usually find me playing chess.
