Website for room replenishment management

I did not start the project, but I continued its support / improvements, and made a lot of changes in terms of fixing bugs, created a responsive design (there was a lot of synchronous code and during database requests the web page would "hang") pagination. There were also many fixes on the backend side regarding the optimization of database queries. The project is evolving and new functionality is constantly being added.
