At AmericanExpress, I verified analytical outputs against source data and identified discrepancies in SQL queries, joins, filters, and aggregations.
I implemented structured data evaluation workflows for KPI reporting, anomaly investigation, and data refresh validation. I also documented AI output accuracy and data discrepancies to support improvements to analytical workflows.
At HuggingFace, I designed, trained, and deployed machine learning models for customer behavior prediction and fraud detection. One model achieved a 20% improvement in customer behavior prediction accuracy, and I applied NLP techniques to customer support workflows.
