Predicting which people would be likely to convert from free users to premium subscribers in the next 6 month period, if they are targeted by our promotional campaign.

(WIP): 'Aporia' in Greek means 'inconsistent'. A Python library that detects and fixes dataset issues using both rule-based methods and ML models. It evaluates dataset quality across multiple metrics, including missing values, duplicates, outliers, class imbalance, and label consistency. It also suggests fixes based on the metric scores.

Supervised Learning project from TripleTen

End-to-end credit risk scoring system using XGBoost, SHAP, and threshold tuning to predict loan defaults and automate lending decisions.

Developing a machine learning model to predict customer churn as it is essential for proactively retaining valuable customers.

End-to-end machine learning workflow on the Combined Cycle Power Plant dataset: data cleaning, EDA, outlier removal, feature engineering, class balancing, and model evaluation for regression and classification. Includes code, visualizations and best practices in a single Jupyter notebook.

Developed an ensemble ML classification model to predict U.S. visa case outcomes (Certified vs Denied) using applicant and employer attributes. Performed EDA, sampling, and model tuning (Random Forest, Gradient Boosting, XGBoost) to improve decision efficiency and identify key policy drivers like education, experience, and wage trends.

This project focuses on detecting fraudulent credit card transactions using Machine Learning and Data Analytics. It applies advanced techniques such as EDA (Exploratory Data Analysis), feature engineering, and imbalance handling (SMOTE, undersampling) to improve fraud detection accuracy.
