theerealhenry/Loan-Default-Prediction-Project

This project focuses on building a robust and generalizable machine learning model to predict the likelihood of loan default using customer, loan, and macroeconomic data. The solution is developed as part of a real-world financial risk modeling challenge and emphasizes performance across different African markets, specifically Kenya and Ghana. # 💳 Loan Risk Intelligence System > 🚀 **Production-grade machine learning platform for real-time and batch loan default prediction, featuring explainable AI, portfolio analytics, and scalable deployment.** --- ## 🌐 Live Application 🔗 **Streamlit App:** loan-default-risk-app.strea… 🔗 **GitHub Repository:** github.com --- ## 🎥 System Preview ### 🏠 Main Dashboard ### 🔮 Single Loan Prediction ### 📊 Portfolio Analytics ### 🧠 Model Explainability (SHAP) --- ## 🎯 Problem Context Financial institutions must accurately assess **loan default risk** to minimize losses and optimize lending decisions. This challenge becomes significantly more complex in **emerging markets**, where: - Customer behavior is heterogeneous - Economic conditions are dynamic - Data distributions vary across regions This system is inspired by real-world financial data from the **AI4EAC Finance Challenge (Zindi)** and is designed to: ✔ Generalize across markets (Kenya & Ghana) ✔ Handle class imbalance and noisy features ✔ Provide **interpretable, production-ready predictions** --- ## 💡 Solution Overview The **Loan Risk Intelligence System** is an end-to-end machine learning platform that enables: - 🔮 **Real-time loan risk prediction** - 📊 **Batch portfolio risk analytics** - 🧠 **Explainable AI (SHAP-based insights)** - 🎯 **Risk segmentation & decision support** The system is designed to replicate a **real-world fintech credit scoring engine**, combining predictive accuracy with transparency and usability. --- ## 🏗️ System Architecture Raw Data → Feature Engineering → Model (LightGBM) → Inference Layer → Risk Segmentation → Streamlit UI (Real-Time + Batch + SHAP) ### Key Design Principles: - Modular pipeline (separation of concerns) - Config-driven architecture (YAML) - Reproducible training & inference - Production-ready deployment --- ## ⚙️ Key Features ### 🔮 Prediction Engine - Single-loan rea …
