Labeling Experience

Credit Card Fraud Detection — Independent Project (AI model training & evaluation)

Built and evaluated credit-card fraud detection models using supervised classification workflows in Python and SQL. Focused on EDA, cleaning, transformation, and model evaluation using standard metrics and a confusion matrix to support anomaly detection decisions. The work aligns with AI training and labeled-data preparation through systematic data processing rather than manual annotation. • Performed EDA and data cleaning to transform transaction features into model-ready variables • Trained classification models in Scikit-Learn and assessed Precision, Recall, and F1-Score • Used confusion matrix analysis to optimize detection while minimizing false negatives • Designed an end-to-end pipeline for risk mitigation using anomaly detection modeling

2026 - Present

Salifort Retention Project — Independent Project (AI training & model evaluation)

Developed an employee turnover prediction system as a supervised ML project using data processing and model training practices. Conducted EDA and feature engineering to identify factors related to churn and improve classification performance. The activity represents AI training with labeled outcomes through systematic dataset preparation and validation. • Cleaned, transformed, and analyzed HR-related data using Python, Pandas, and NumPy • Implemented feature engineering and variable-importance analysis for churn drivers • Trained and evaluated Scikit-Learn classification models with Precision, Recall, and F1-Score • Built interactive Streamlit dashboards to communicate predictions and insights
