At UnitedHealth Group, I designed and implemented an AI inference platform for enterprise healthcare, building fault-tolerant model-serving systems with Python and FastAPI. I also optimized GPU utilization and helped establish MLOps practices for deployment, monitoring, and rollback.

At Oracle Health, I engineered AI applications and RAG pipelines that reduced information retrieval time by approximately 40%. Earlier, I developed backend services at Google and worked on Stripe’s payments infrastructure.
