🧠 Market Price Scraper

A multi-threaded UWP desktop application that scrapes product data from Amazon and eBay, storing it in a local SQLite database and visualizing historical pricing using interactive charts.

This was built to explore concurrent scraping, lightweight persistence, and data-driven UI components — combining front-end and back-end logic .
