United States

Message

At Twitch, I own architecture for data and AI/ML infrastructure supporting live-streaming products. I built foundations for embeddings, semantic search, and RAG workflows, connecting document processing, chunking, vector databases, and evaluation.

I also designed event-driven data services and developed ML-ready datasets and feature pipelines. At Capital One, I built backend applications and governed data workflows for financial-services systems, with secure APIs, testing, and auditability.
