A basic e-commerce website

We have to build an basic django and flask e commerce web application. So i have 5 microservices i.e user service, product service, cart service , order service, and review service. And order and review services need to be implemented in my project. When the user clicks on checkout button in cart the items should be moved to order service with all the details and in the order page user can select his/her address during logged in. Or they can add a new address which can save into database with same user_id. And there should be an option to check all the orders that are placed and moreover when the order got checkedout inventory count should be reduced Review service should be done in flask Coming to review service .. a user can add review to a product. And other can see that reviews that are added by other users. So i built other 3 services... So i want these two to be done on before 19th March evening
