Hello there, I can make the management app for you.
To do so, I'll use the best web design tools/techniques for a great user experience. We need to define the requirements of the project in order to make it, but I can guarantee you I can make a simple, easy to use, with all the required functionalities you need, such as task scheduling, resources management, login system, and so on.
Please let me know exactly what you need in order to start the project.
Best Regards,
Jaqueline Passos
