Chiper

Improvement of the mobile application in the area of shopping/recommendations. I recommended changes to improve the speed of the add to cart action. I implemented changes to the global state and We went from more than 4 seconds to add, to less than a second. I was also in charge of refactoring components and created the most used component of the app, the product carousel. My way of writing code was taken from the example to redo the architecture of the application code
