WORK HISTORY
Ml Developer Ii in Information Technologies @Ricoh USA, Inc.
Exton, PA, US
Data Quality Framework: Engineered a distribution-free data quality assessment framework for time-to-event prediction, accelerating analysis from three months to one day (99.6% reduction).• Multi-Horizon Forecasting: Developed a multi-horizon time-series forecasting model for customer churn prediction.• Cross-Sell Recommendations: Built a recommendation system combining Transformer-based attention mechanisms and Graph Neural Networks (GNNs) for context-aware customer segmentation.• Legacy Code Remediation: Analyzed over lines of legacy Python code for time-to-churn prediction and corrected seven critical issues, including two conceptual mathematical errors that caused incorrect predictions.
