I have been deeply involved in the development of an iOS mobile application for a B2B service offered by Sberbank. The architecture of the application follows the MVVM+C (Model-View-ViewModel with Coordinators) design pattern. The user interface is built using UIKit, combining both storyboard-based layouts and custom UI elements created programmatically. To manage dependencies, we use CocoaPods and partially Swift Package Manager (SPM) for certain packages. Our app leverages Combine for reactive programming and binding, enabling seamless data flow. For dependency injection, we employ Swinject. We've also implemented Alamofire for our networking layer to ensure efficient communication with the backend services. To handle concurrency and make our app more responsive, we utilize GCD (Grand Central Dispatch) along with active adoption of async/await for multithreading.Additionally, our app incorporates the 2GIS iOS SDK, which enriches our user experience with advanced mapping and geolocation features for navigation.My responsibilities encompass a wide range of tasks, including:1. **Support and Bug Fixing:** Ensuring the smooth operation of the existing app by providing timely support and addressing any reported bugs.2. **New Feature Development:** Actively participating in the development of new features and enhancements. Our project has reached the MVP stage and is continuously evolving, with plans to roll it out to major domestic enterprises.3. **Technical Interviews:** Conducting technical interviews for potential iOS developers to expand our team. This includes assessing their skills and qualifications to ensure they align with our project's requirements.4. **Code Reviews:** Regularly conducting code reviews to maintain code quality, consistency, and best practices within the development team.

I have been deeply involved in the development of a language learning service, which aims to help users learn foreign languages effectively. Here are some of the key aspects of my work on this project:1. **User Interface Development:** I have been responsible for crafting and refining the user interface of the app. This involves creating visually appealing and user-friendly screens using UIKit, and incorporating new features and enhancements with the help of CocoaPods.2. **SwiftUI Development:** In addition to UIKit, I have been actively working on a new version of the application using SwiftUI. This allows for a more modern and intuitive user experience.3. **JSON Parsing and REST API:** To ensure the app can provide users with the necessary language resources and connect them with native speakers, I have implemented JSON parsing for handling data and integrated REST APIs to fetch relevant information.4. **Bug Fixing and Legacy Code:** Addressing and resolving bugs and issues in the app, including dealing with legacy code to make the application more stable and efficient.5. **Synchronous and Asynchronous Requests:** I have experience in working with both synchronous and asynchronous network requests to provide seamless communication with the backend services, ensuring a smooth user experience.6. **Motivational Program:** I have contributed to the development of a motivational program within the app to keep users engaged and motivated in their language learning journey.7. **User-Generated Dictionary:** Our app features a user-generated dictionary, which I have helped implement and maintain. Users can contribute to this dictionary, enriching the language learning experience for others.Working on this project has allowed me to combine my technical skills with a passion for language learning, contributing to the creation of a valuable tool for users looking to enhance their language proficiency.
