A full-stack AI-powered product recommendation engine that analyzes customer behavior, purchase history, and preferences to deliver personalized suggestions. Built with a Python Flask backend and React frontend, this solution implements three core recommendation algorithms: collaborative filtering (user-based and item-based), content-based filtering using TF-IDF vectorization, and a hybrid approach that combines both methods for improved accuracy.
 
Designed for developers, agencies, and e-commerce businesses seeking to add intelligent product recommendations to their platforms. The system includes a complete REST API with endpoints for user recommendations, similar products, trending items, interaction tracking, and analytics. A web-based dashboard provides access to system statistics, product catalogs, recommendation testing, and performance metrics including click-through rates and conversion tracking.
 
Key capabilities include:
Multiple recommendation algorithms with configurable weights
Cold-start handling for new users and products using popularity-based fallbacks
Price, category, and stock availability filtering
Model training pipeline with evaluation metrics (Precision@K, Recall@K, NDCG, Coverage, Diversity)
Synthetic training data generator to improve coverage and protect user information
SQLite database with SQLAlchemy ORM (upgradeable to PostgreSQL)
Comprehensive API documentation and architecture guides
Unit tests for API endpoints, data processing, and recommendation algorithms
Setup scripts for Windows, macOS, and Linux
