In my 1-year React Native Development process, I developed more than 5 applications, one of them is the Vehicle Tracking System named "netrapor", in this project, it is aimed to send notifications to the managers of the tracked fleets in case of violations. Firebase's notification systems were used and worked with RESTful API. My other applications are mainly E-Commerce Systems, RESTful API, firebase services were used in these applications. Below are a few screen outputs from the projects I have developed.

I used Xamarin and Swift for mobile application development
