Big Data development in a company that creates a national commodity labeling system (provided by matrix barcode) in the Analysis Platform department. The company gets real-time data from all suppliers, manufacturers, and distributors of all commodities and transactions in the country. Provided by this data our team created some path of commodity from the appearance of it in the country (by manufacturing or importation) to the end buyer. Then we provided an opportunity to each customer at every step of the commodity path to check the authenticity of the commodity. Customers can check it by matrix barcode label by our application. We were working with such commodity categories as milk products, water, pharmaceutical products, covid vaccination, tobacco, alcohol, and all light industry products. Inside my department I created some data infrastructure and pipelines to consolidate this data for various reports and analysis country's economic situation in these markets.
