+    ## 🎯 Problem Statement
+    
+    Amazon's Region Flexibility Engineering team needs to optimize service placement across 
+    AWS regions to:
+    - **Reduce latency** for end users
+    - **Lower costs** by avoiding expensive regions
+    - **Maintain reliability** with appropriate redundancy
+    - **Support rapid global expansion**
+    
+    ## 🛠️ Solution Architecture
+    
+    ### 1. Data Pipeline
+    - **Sources**: Service metadata, traffic patterns, regional latency, placement history
+    - **Processing**: SQL queries + Pandas for feature engineering
+    - **Scale**: 150+ services, 5 regions, 1.6M+ traffic records
+    
+    ### 2. ML Models
+    
+    **Model 1: Latency Prediction (XGBoost)**
+    - Predicts service latency for a given placement
+    - Features: Memory, CPU, traffic patterns, outbound latency
+    - Performance: RMSE = 28.7ms
+    
+    **Model 2: Placement Strategy (Random Forest)**
+    - Classifies services as high/low traffic
+    - Determines optimal number of regions per service
+    - Accuracy: 100% on test set
+    
+    ### 3. A/B Testing Framework
+    - **Control**: Random service placement (baseline)
+    - **Treatment**: ML-optimized placement
+    - **Results**: 5.25% latency reduction, 4.92% cost savings, statistically significant (p < 0.001)
+    
+    ## 📊 Key Metrics
+    
+    | Metric | Result |
+    |--------|--------|
+    | Latency Reduction | 5.25% |
+    | Cost Savings | 4.92% |
+    | Critical Service Improvement | 9.30% |
+    | Statistical Significance | p < 0.001 ✅ |
+    | Placement Efficiency | 378 vs 452 pairs (-16%) |
+    
+    ## 💻 Tech Stack
+    
+    - **Data**: SQLite, Pandas, NumPy
+    - **ML**: scikit-learn, XGBoost
+    - **Statistics**: SciPy (t-tests, significance)
+    - **Visualization**: Plotly, Streamlit
+    - **Deployment**: Hugging Face Spaces
+    
+    ## 📚 How to Use
+    
+    1. **Overview**: See project summary and data distribution
+    2. **A/B Results**: Detailed comparison of strategies with statistical validation
+    3. **Regional Analysis**: Explore latency patterns across AWS regions
+    4. **Service Details**: Interactive explorer for individual services
+    
+    ## 🚀 Next Steps for Production
+    
+    - Integrate with real AWS CloudWatch metrics
+    - Deploy as automated recommendation engine
+    - Create feedback loop for model retraining
+    - Build alerting system for anomalies
+    - Extend to multi-cloud (GCP, Azure)
+
