About
Data Scientist & AI Architect shipping production-grade systems
I’m a Data Scientist and Generative AI Engineer with 4+ years building and deploying ML systems across the full lifecycle — data to deployment.
At BNY, I build production GenAI for fraud detection, document intelligence, and transaction monitoring — focused on reliability, scale, and observability.
Previously at Vivma Software, I built ML and NLP systems for churn prediction, forecasting, and recommendations.
