● Developed a high-quality iOS application using Swift, SwiftUI, and MVVM architecture. I followed software development best practices and used standard technologies such as WebRTC, WebSocket, SocketIO, MediaSoup, DI, Combine, SOLID, RESTful, and gRPC. I also ensured secure CoreData storage by using keychain and AppStorage.● By adopting best practices and implementing the MVVM architecture, Swinject for dependency injection, and the router pattern for network layer communication, I created… Show more ● Developed a high-quality iOS application using Swift, SwiftUI, and MVVM architecture. I followed software development best practices and used standard technologies such as WebRTC, WebSocket, SocketIO, MediaSoup, DI, Combine, SOLID, RESTful, and gRPC. I also ensured secure CoreData storage by using keychain and AppStorage.● By adopting best practices and implementing the MVVM architecture, Swinject for dependency injection, and the router pattern for network layer communication, I created an efficient and scalable codebase. I optimized performance and reliability with frameworks like Combine and Alamofire.● The resulting codebase can be viewed on my Github and demonstrates my expertise in these methodologies. I improved navigation issues by implementing MVVM + R with the router pattern, resulting in a 30% improvement in navigation performance and a better user experience. The application generated the desired output for Palphone, an emotional-based, highly secure communication app.(social media) Show less
