Constructed large-scale datasets with 22,000+ observations for exploratory and quantitative analysis, producing statistical and geographic visualizations
Sourced, merged, and cleaned public datasets using Python (Pandas, NumPy), with additional data collected through API extraction and web scraping (BS4)
Created new metrics and conducted data visualization, descriptive statistics, and OLS/multiple regression analysis
Applied Lasso, Ridge, Elastic Net, clustering, Random Forest, and XGBoost with hyperparameter tuning
Solo-authored the research paper in Overleaf with LaTeX and used GitHub for version control
Skills: Pandas, Numpy, BS4, OLS, Lasso, Ridge Regressions, Clustering, Random Forests, XGBoosting, API Data Extraction, Web Scraping, GitHub Version Control
Analyzed 12,700+ Lending Club loan records to identify key borrower and loan characteristics associated with default risk
Cleaned and transformed data by addressing missing values, encoding categorical variables, and standardizing features for machine learning models
Built and compared seven classification models, including Logistic Regression, Random Forest, AdaBoost, and XGBoost, using cross-validation and GridSearchCV for model optimization
Evaluated models using accuracy, precision, recall, confusion matrices, ROC/AUC, and training time; XGBoost achieved the strongest performance with 77.71% test accuracy
Analyzed feature importance and optimized classification thresholds based on the financial costs of false predictions, recommending a 0.3 threshold for XGBoost
Skills: Python, Pandas, NumPy, Scikit-learn, XGBoost, Cross-Validation, GridSearchCV, Data Visualization, ROC/AUC Analysis
Analyzed financial statement data for 170+ public companies, evaluating profitability, efficiency, leverage, and return on equity across industries using the DuPont framework
