- Develop features by combining Flutter framework with iOS frameworks for the declarative UI.
- Handle communications between Flutter and iOS by method channel and streams.
- Improve Flutter video performance by integrating Texture rendering with pixel buffer reading.
- Integrate GPUImage and Metal framework for image processing and rendering.
- Flutter usages: Notification, ValueNotifier, StreamController, Provider, Bloc, GlobalKey, and so on.
- Build preprocessing mechanism, draft mechanism, local notification mechanism, gamification mechanism.
- Handle UI features and business logics.
- Handle CRUD operations with sqlite.
- Bugs resolving and issues tracking.
- Build stateless widgets with RiverPod framework.
- Build reusable widgets with gestures.
- YouCam Toolkit (SwiftUI / Swift)
- Develop features with SwiftUI and Combine framework under the VIP architecture and the concept of declarative UI.
- YouCam for Business (Swift / Objc)
- Build contactless features with gesture recognition and voice recognition for the B2B project to deal with COVID-19.
August 2018 - February 2020
iOS Software Engineer at Masterwork Aoitek Co. Ltd. Taipei. Taiwan.
- Lollipop - smart baby monitor (swift / Objc)
The Lollipop app provides services that are related to 24/7 live streaming and works closely with backend services and the hardware devices. 10k+ users. with 97% crash-free rate.
- Refactor most of the codes with Swift and MVVM design pattern from Objective-C and MVC.
- Introduce data-driven development (DDD) to the app by changing how app works with local database.

Education
M.S. Degree of Computer Science and Engineering
NSYSU. Graduated in 2018.
B.S. Degree of Library and Information Science
NTU. Graduated in 2016.
Thesis & Research
I had proposed a conference paper improved quantum-inspired evolutionary algorithm on IEEE SMC in 2018, which solved data clustering problem with better results and performance.
Medium
I shared what I learned in iOS development by writing technical articles in Medium. Also, I joined the Medium's largest active publication The Startup and Flawless iOS as an approved writer.
