PROJECT EXPERIENCE

Telecom Customer Churn Prediction
github.com/Bartmanskiy/goit-ds-hw-final_project

Metrics: Accuracy: 94.1% | F1-Score: 94.6% | Tech: Python, Scikit-learn (Random Forest, GridSearchCV), Streamlit, Docker
• Developed an end-to-end classification model to forecast customer churn in telecommunications service data.
• Performed extensive data cleaning, exploratory data analysis (EDA), and feature engineering to identify key churn indicators.
• Optimized Random Forest hyperparameters using GridSearchCV, achieving outstanding metrics (94.1% Accuracy, 94.6% F1-score).
• Designed an interactive web interface using Streamlit and containerized the end-to-end application using Docker for scalable
deployment.
