My role and work

As an iOS Engineer at MegaProgramming, I developed and refactored native iOS functionality using Objective-C, C++, UIKit, and Model-View-Controller (MVC) architecture, applying clean code practices and reusable software components.

Engineered real-time product price, discount, and inventory synchronization using WebSockets, addressing changing prices, promotions, and stock availability when multiple customers were purchasing products. Implemented Core Data persistence and native iOS caching strategies to improve responsiveness, reduce redundant requests, and keep product information current.

Contributed to secure payment workflows, user authentication, and responsive UI development. Refactored code for maintainability and reuse, applying object-oriented programming (OOP) and Auto Layout to support multiple iPhone sizes without separate device-specific implementations.
