Built the Efí's iOS app by architecting the project with a focus on the UIKit framework, iOS 13, and the efficient VIPER architecture.In this role, I undertook the following key responsibilities:• The development and continuous enhancement of the app's diverse feature set.• The utilization of TestFlight and Firebase App Distribution to streamline the distribution of beta versions, ensuring a robust testing environment and comprehensive user feedback.• I managed the app's launch on the App Store, maintaining a proactive approach to promptly release subsequent updates and versions.• Took charge of a team of three adept iOS developers, providing decisive leadership in the critical process of refactoring the core functionality responsible for updating user transfer limits.My main contributions to the project included the implementation of feature flags using Firebase Remote configuration, which allows us to toggle features that are currently in production without having to upload a new version to the store. Another contribution was the creation of a library that abstracts the configuration of new attributes to a label, like different fonts and colors in a same label, an image between two texts, etc. This technology has enabled us to significantly reduce the time required to complete this kind of task, reducing the number of visual errors we encounter and enhancing the user experience.

I started by taking part in a training program within the company to learn how to build native iOS apps, so I learned the main architectures like MVC, MVVM and MVVM - C. I also learned how to use both UIKit and SwiftUI, and then I learned how to build tests to these frameworks.Then within the Growth team, I held a pivotal position. My responsibilities included meticulously mapping out all the key features of the app and establishing comprehensive deep-link routes to various product types within the application. This strategic approach enabled the app to seamlessly guide users to advertised products through notifications, resulting in a notable boost to the company's revenue. I was also responsible for proficiently designing and implementing all the necessary redirections that occur when users interact with these notifications.Furthermore, I successfully addressed a memory leak issue that affected the app's main features. To achieve this, I meticulously identified and eliminated unnecessary observers, which had been causing perplexing behaviors throughout the app. These behaviors were primarily rooted in improper utilization of RXSwift features.In essence, my contributions encompassed both refining the app's functionality and enhancing its performance, ultimately contributing to an improved user experience and the company's overall success.
