At Ziyøn, I worked on developing an iOS app in SwiftUI, using the MVVM architecture. My responsibilities included code refactoring, bug fixing, screen creation, API integration using URLSession, and Firebase integration (Auth, Storage, Crashlytics). Additionally, I contributed to the development of components with a proprietary framework managed via SPM (Swift Package Manager). Deliveries followed agile principles, supported by Atlassian tools (Confluence, Jira Software, and Bitbucket), ensuring efficient project management.Hard Skills:- Swift (Programming Language)- SwiftUI- Reactive Programming with Combine- Componentization- MVVM Architecture (Model-View-ViewModel)- Clean Code- Data Persistence (CoreData and UserDefaults)- Firebase- URLSession (Integration with Restful/Webservice APIs)- GitFlow- Swift Package Manager- Atlassian Tools (Confluence, Jira Software, Bitbucket)App Store Link: https://apps.apple.com/br/app/ziyon/id6472515772Additional Information: In addition to my experience at Ziyøn, I have been dedicating myself to studying ViewCode, applying MVVM architecture, Restful/Webservice API integration, SOLID principles, dependency injection, design patterns such as Singleton, and reactive programming with delegates. I have also been exploring concepts like Factory Method and unit testing with Spy, although I have not yet applied these two concepts in projects. All this learning has provided me with a solid foundation to develop efficient and scalable solutions for iOS.
