Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Telco Customer Churn Classifier

Beginner

Build a complete churn-prediction pipeline using the classic Telco Customer Churn dataset. Perform EDA, engineer features, train a logistic-regression and random-forest classifier, handle class imbalance with SMOTE, and evaluate with PR-AUC and lift curves. Deploy the best model as a Flask API.

SaaS Churn Prediction with Gradient Boosting

Intermediate

Using a synthetic or open SaaS usage dataset, build a LightGBM churn model with time-based cross-validation. Engineer rolling-window engagement features, tune hyperparameters with Optuna, explain predictions with SHAP, and track experiments in MLflow.

LLM-Augmented Churn Risk Scoring

Advanced

Combine structured behavioral data with unstructured support-ticket text. Use Hugging Face sentence-transformers to create ticket embeddings, feed them alongside engineered features into a gradient-boosting model, and use the OpenAI API to generate per-customer natural-language churn explanations powered by SHAP values.
