Hello. I am in need of a scraper expert who is also able to build a robust Discord system to manage said data and alert users based on keywords. In a very niche market where websites are relatively easy to scrape. 10-25 retail sites. 6-7 P2P and forum sites. Product must be serviceable with bot health systems. Scraper should gather and alert on: - retail site in stock as it comes up - P2P product descriptions, price, preview, etc - keyword updatable - scalable with users - discord and/or signal integration - minimal monthly cost - local computer host. (No droplet) Ideal Skills and Experience: - Proficiency in web scraping tools (e.g., BeautifulSoup, Scrapy) - Experience with P2P marketplaces - Ability to handle large volumes of data - Knowledge of data storage solutions (e.g., databases, CSV files)
