🏅 Olympics Summer & Winter Analysis

---

📌 Overview

This project provides a complete end-to-end analysis of historical Olympic data from both Summer and Winter Games. It combines data analysis, feature engineering, and machine learning to uncover insights about country performance, medal trends, and participation patterns.

The project is designed using a production-level machine learning architecture, making it scalable, modular, and easy to extend for real-world applications.

---

🎯 Objectives

• Analyze historical Olympic datasets (Summer & Winter)
• Clean and preprocess raw data
• Perform exploratory data analysis (EDA)
• Engineer meaningful features
• Build machine learning models (regression & classification)
• Evaluate model performance
• Create a reusable ML pipeline structure

---

📊 Dataset
