Crawler/Search Service for E-Commerce Data -- 2

I'm seeking an experienced developer to create an online crawler/search service. This will need to be compatible with both web and mobile platforms. It should be capable of collecting product details, pricing information, and reviews and ratings. I have specific third-party e-commerce websites in mind for this crawler to search and collect data from. A successful freelancer will demonstrate a strong background in full stack development and data collection technology. Relevant experience with e-commerce platforms will be highly valued. Overall, the right individual should be capable of handling all aspects of this project, from initial design stages to final implementation.
