  Mar 2023 - Present

  MarkTong- A service that facilitates communication between individuals and patent attorneys for patent application purposes.- Skills: SwiftUI, MVVM, Combine, Swift Concurrency, Alamofire, Firebase, UserNotifications, PreferenceKey- Description: I am Responsible for maintaining MarkTong and implementing new features. I have refactored the app structure that was originally built with UIKit into SwiftUI. Additionally, I’ve implemented real-time chat functionality using Firebase Realtime Database and integrated push notifications through FCM (Firebase Cloud Messaging) to receive alerts for chat messages. Furthermore, I've removed the installed libraries and designed custom UI components, including a segmented control, bottom sheet, sticky header view, side menu, and more. In networking, I’ve used Combine and Swift Concurrency to remove redundant code and nesting structure with escaping closures. Lastly, I’ve fixed features that weren’t working well while refactoring.
