As a Statistical & ML Modeling Expert, I developed and deployed machine learning models for financial risk assessment, enabling more precise credit granting decisions for corporate vehicle financing. Beyond model development, I built scalable ML pipelines, optimized data architectures, and integrated data-driven methodologies to improve financial decision-making. 📌 Risk Modeling & Deployment: Built ML models (XGBoost, Bayesian inference) reducing financial risk exposure by 50% while increasing credit approval rates by 20%, 📌 ML Pipeline Automation: Developed end-to-end MLOps workflows (CI/CD, Docker) for scalable model deployment and monitoring, 📌 Frequentist Statistical Analysis: Designed data-driven metrics to assess business introducers’ related risk, 📌 Data Enrichment & Feature Discovery: Integration of new data sources (macroeconomic indicators, alternative financial data) to boost model accuracy, 📌 Tech Stack Transformation: Led migration from old to no/low-code data architecture stack, streamlining data workflows for low-code analytics adoption and improving data integration workflows for models
