+*Let's see how it is possible to create a circular carousel with parallax effect in React Native.*
+

+
+Recently, during a one-to-one meeting with my engineering manager, [Luca D'antona](https://www.linkedin.com/in/lucadantona/), 
+we discussed some exciting animations we’d like to bring to our mobile apps at [lastminute.com](https://corporate.lastminute.com).
+In particular, Luca pointed out how captivating the carousel on the home screen of the official  
+[Apple TV app](https://www.apple.com/apple-tv-app/) is. This carousel stands out for its stunning parallax animation.
+Essentially, as you scroll through the images of TV shows/movies, the images shift based on the scroll position,
+adding a dynamic sense of motion to the entire experience. 
+In our apps we have been using [React Native](/2018/07/04/react-native-typescript-existing-app/) for quite some 
+time, but animations often have a bad reputation within this framework.
+Luca challenged the team, asking: “Do you think it’s possible to implement such a cool animation on our daily deals carousel? ChatGPT says it should be possible!”
+I took this challenge personally because I’m passionate about animations—a natural consequence of my love for 
+[computer graphics](/2017/08/25/how-to-calculate-reflection-vector/)).
+And here I am today, having successfully implemented the challenge and enhanced our daily deals carousel with this 
+new, beautiful parallax effect.  
+In this post, I’ll show you how to create a stunning full-screen circular carousel (that you can scroll endlessly) 
+with a parallax effect on the images and an opacity animation for the text descriptions of each item. Below, you can 
+find a video of the final result.

+
+To develop this carousel we will use:
+
+* Expo
+* React Native Reanimated
+* Expo Linear Gradient
+
+#### Implementation
+
+Let's start from the implementation of the main carousel component, `ParallaxCarousel`.
+This component is the one responsible for displaying the items and managing the scroll.
+In particular, it has the responsibility to simulate the circular endless loop during the scroll.  
+
+
+#### Conclusion
+
+You can find the full implementation of what I described above in this [github repo](https://github.com/chicio/React-Native-Parallax-Carousel).
+It was quite funny to implement this carousel and the parallax animation.
+I hope I can add more animation during my FriYaY to improve our apps UX :heart:.
