Retail Inventory Monitoring & Restock Alert Developer

I need a developer to build a retail inventory monitoring and restock-alert tool for products such as NeeDoh toys, Pokémon products, Pop Mart, and other collectibles. The system should monitor publicly accessible product information, including availability and price, and notify me when qualifying products become available. It should include a simple dashboard where I can enter product URLs, keywords, maximum prices, and preferred retailers. The project must use authorized APIs or other methods permitted by each retailer’s Terms of Service. It must not bypass CAPTCHAs, access controls, purchase limits, queues, or anti-bot protections. No automated purchasing or checkout is required. Desired features: Product URL and keyword monitoring Price and availability tracking Email, text, or desktop restock alerts Maximum-price settings Monitoring history and status Easy-to-use dashboard Source code and setup instructions Ongoing maintenance option Please describe your experience with compliant inventory monitoring, authorized retail APIs, product feeds, and alert systems.
