My role and work

As an iOS Engineer at Arm-BoldMind, I developed native iOS functionality using Swift, UIKit, MVC architecture, Auto Layout, and XIB-based interfaces, implementing coupon discovery, purchasing, QR-code activation, user authentication, business profiles, favorites, and transaction history.

Worked extensively with RealmSwift and Core Data, using Realm as a local persistence layer to improve application responsiveness and reduce repeated network requests. Implemented data synchronization with shared backend services, keeping locally stored information consistent with updates originating from the website, Android application, and other users.

Integrated Alamofire, ObjectMapper, and SwiftyJSON for API communication and data mapping, alongside Google Maps SDK for iOS for location-based deal discovery.

Contributed to Firebase integrations, social authentication, push notifications, and Idram payment functionality, supporting a responsive and connected mobile commerce experience.
