The task was to make a web scraper for several online supermarkets. It was built as a stable, robust, and schedule-running tool. If the scarping stops due to network failure or other reasons, the scraper continues from the last saved information. The scraper collects the information related to the products over the categories and saves the data into CSV output as well as into MySQL database.

Asynchronous web scraper works with the ElasticSearch cluster and MongoDB. It takes the list of organizations from MongoDB database and creates the bulk of tasks (coroutines) that run asynchronously. For every organization in the database, it crawls all the pages, clears the texts, and updates ES cluster with new text content. It saves all necessary things into draft ES index including sitemaps, visited pages, visiting reports, "robots.txt" rules.

Supermarkets data scraping using Python
Pavlo is a reliable and proficient fullstack developer. He recognizes the different scenarios that arise after the software development has started and works smartly to address such scenarios to deliver a high quality software product as required by the end-user. He keeps the communication open and regularly informs about the progress. Please do not take advantage of his good nature by demanding more for the same fixed price, if project requirements increase do pay him more. Strongly recommended
