I’m a Senior AI/ML Engineer who builds recommendation and discovery systems that turn signals into better experiences. At Disney Streaming, I architected personalized content discovery and drove improvements to title recommendations across homepage carousels.

I focus on end-to-end ML: from modeling and ranking to operational reliability. I engineered “Because You Watched” capabilities using collaborative filtering, embeddings, metadata, and vector similarity retrieval, and I designed cold-start pipelines for new releases to improve launch-week discovery.

I also build the infrastructure that makes modern AI usable in production. I designed RAG-ready content intelligence using semantic chunking, vector indexes, and metadata filters, then prototyped LLM-assisted catalog-enrichment workflows with structured outputs and human-in-the-loop review.

To keep systems dependable, I operationalize personalization workflows with Airflow, Docker, Kubernetes, CI/CD, and model registry patterns. I established observability through feature-drift detection, freshness checks, latency monitoring, and prediction/engagement analytics to diagnose model degradation and improve reproducibility.
