Can you tell about your main responsibilities and projects you participated in at previous workplaces?

In my previous jobs, my main responsibilities included developing and maintaining iOS applications, participating in architecture design and performance optimization. I worked with UIKit and SwiftUI, integrated REST APIs, implemented data processing, and ensured application stability.

For example, in one project, I was involved in creating an e-commerce app, where I was responsible for implementing the user interface and server interaction, as well as introducing offline access features and data caching to improve user experience.
