At ORIZON, I built four predictive models that improved healthcare audit efficiency by 50% and deployed models processing 1 million audit cases monthly at 96% accuracy.
I've also developed OpenAI API and LangChain workflows that save 60 hours monthly, while supporting 120 healthcare providers with causal inference. Previously at ANALYSIS, I built churn models across 900 million customer records, reduced attrition by 15%, and optimized ETL pipelines handling 3TB daily.
At SAS, I analyzed 5 million financial transfers, identified process bottlenecks, and helped generate R$1 million in annual savings through predictive analytics.
