Previous developers refused to continue working on the project. We faced the tasks of fixing bugs on the frontend, finalizing the functionality of the server-side and eliminating security vulnerabilities.
We analyzed legacy code, fixed bugs, provided secure access to the service, developed a registration system, automated the addition of goods from the VK social media site.
Items from user orders get on the general purchasing list. The closest operator purchases the goods and updates the status on the list page. The problem was that the status of the order was not always displayed correctly, which caused operators to buy goods more than ones.
We solved the problem by adding validation of sending the request to the server. We also developed a mobile version of the list page so that employees can update their status immediately after purchase.
