App from App Sheet for employee schedules that are made through excel. The app needs to show employees only their specific schedule, Notify when asks offs are due, send notifications when new schedules are published.

Hello, I'm in the market for an app from App Sheet that will handle employee schedules that are made through excel. The app should be designed for iOS and feature the following specifications: it should show employees only their specific schedule, notify when asks offs are due, send notifications when new schedules are published. I already have some ideas about how to design the app, but I'm open to other suggestions. In terms of features or functionalities beyond these, I'm not sure what else it would need, so I'm open to suggestions. I'm looking for an experienced developer to bring this project to life. Attached is a picture of what we usually print for employees. We want it to be easy to read and easy to use.
