Created an application for automatic Web Scraping of products (their details and images). The application's purpose was to generate Excel reports and upload the products automatically to a new designated drop shipping site. Products were taken from various partner manufacturers Business-to-Business (B2B) systems and databases.The majority of the driving code was implemented in Python, with a logging system set up for each transaction. The data was extracted from websites using Selenium or by retrieving JSON responses from the server API. Data extraction, filtering, and uploading was also done using relational SQL and NoSQL (MongoDB) databases.
