Project Goals: To create a centralized hub for Argentine shoppers to find and compare discounts and promotional catalogs from major retailers, eliminating the need to visit multiple sources.
My Solution: I built an automated aggregation platform that scrapes, processes, and displays deals from various online sources. The solution involved developing a custom data pipeline and a responsive front-end with powerful search and filtering capabilities.
Impact: The site attracted a consistent user base by providing a clear and valuable service: saving people time and money. The project validated a real-world need and served as a practical demonstration of full-stack development and data aggregation skills.
