Published 3 app on AppStore and PlayStore iOS Swift, UIKit, Auto Layout, MVVM, RxSwift, APNs. Flutter, Flutter Bloc Clean Architect, FireBase Services. RESTful APIs, Realm Database, Web Socket, Protocol Buffer. My name is Vương, and Ho Chi Minh is my hometown. I hold a Bachelor's degree in Computer Science and have worked in diverse roles, from iOS Developer to Flutter. I am a dedicated and passionate mobile developer with over 8 years of experience in iOS development and 2 years in Flutter. My Flutter project uses clean architecture which have 3 layers: presentation , repository , datasource. Presentation is about the UI and logic of event that user interact. I use Flutter Bloc to makes it easy to separate presentation from business logic. Making your code fast, easy to test and reusable. Repository will make a request to or received data from datasource. I use the Flutter Dio package for make inject Backend services. This have common features like interceptors for authentication. Data is encoded and decoded by JSON serialization for requests and responses. One challenge I faced while developing the project was handling images. There were several challenges related to image features. Storage and Uploading many images to servers take a long time If we not reduce sized of images and make multiple upload at the time. Large memory of image is hard to stored and retrieved. We need to compress to reduce size before upload to network. it help to reduce a lot time for waiting images upload complete . To retrieved and display a lot of images in list view, I have to resize and cache images to guarantee the smooth UI loading but still keep image resolution. Otherwise, reduce size image help reduce memory to storage image which led to memory bloat problem on Flutter. To handle uploading error images, first thing is store the image error to database with specific directory. Delete temporary error image path error when upload complete to reduce memory storage. Adding watermarks to multiple images is challenge of performance and multi progress. Because of large work of adding watermark to single image. It required using isolated threads to prevent UI lagging and improve performance by processing images faster. Other overcome is about Google Map. Load multiple images and build them with markers is very slow. To deal with await async task not complete, I use Future Complete to cancel previous undone task and build aother new data . It prevent undone makers still loading and built to google map.
