This App is designed for Next Door Lounge. It helps the staff to keep track of the reservations and tables of the restaurant. I design it to be easy to use and intuitive. It uses a Firebase as a back-end server and React Native as a front-end. It communicates all changes in real time across all the apps. The solution that I set out to find with this app is about communicating more efficiently with everyone and shorten the amount of time it takes to look at a table that belongs to a reservation. Every night, changes happen: reservations get canceled, tables get switched, and people get added. Everyone should know about these changes, but it takes time to track everyone down, tell them, and make a drawing on their table sheets. That's why thought: What if we could have the table sheet, live on our phone? This way If anyone needs to make a change, we can all see it in real time.
