COMPARI is a full-stack product price comparison platform designed for the Tunisian market. I developed Angular interfaces for customers and administrators, supported by a Spring Boot REST API and PostgreSQL database. The platform includes product search, detailed product pages, seller price comparison, customer reviews, registration, account management, and administration tools. I also implemented web-scraping workflows to collect product and offer data from multiple sellers and organized the solution into separate front-end, user-facing, and back-end modules.
