Machine Learning Engineer & Data Scientist || Statistician

Profile Summary

Statistical Modeller & Data Scientist I am a Statistics professional specializing in building robust predictive models for volatile datasets. I bridge the gap between theoretical statistics and machine learning to solve high-stakes estimation problems. Technical Expertise Predictive Modeling: Advanced implementation of XGBoost, Random Forest, and Ensemble Bagging. Statistical Analysis: Expert in residual diagnostics, addressing heteroscedasticity, and L1/L2 regularization. Feature Engineering: Specialized in target encoding for high-cardinality data and complexity metrics. Optimization: Strong focus on cross-validation (OOF) strategies to ensure model generalization. Key Experience Construction Bid Analytics: Developed a high-accuracy framework for large-scale bidding data, successfully reducing error rates through robust loss functions and seed averaging. Market Trend Modeling: Engineered weighted pipelines to prioritize current market trends and inflation-adjusted pricing. Education Currently pursuing a degree in Statistics, I apply a rigorous mathematical lens to data science, ensuring model reliability (RMSLE) consistently translates from local validation to real-world application.
