## About

```text
At KAVI GLOBAL, I built ETL pipelines and a simulation-based staffing optimization model projecting ~$10M in annual savings. I also improved Snowflake Cortex chatbot accuracy to 94% and developed a RAG chatbot prototype that achieved 85%+ retrieval accuracy in pilot testing.

I’ve applied data science across nonprofit, policy, and automotive work. At HYUNDAI MOTORS, my analysis helped shape autonomous vehicle features and a micro-SUV launch that reached 100K bookings and $120M in revenue; at COMMUNITY DREAMS FOUNDATION CORP, a donor attrition model supported a 15% increase in donor retention.
