Work Experience
Senior Software Engineer • ASUS
Nov, 2017 - Present
ASUS FileManager
Developing and maintaining file management app in Zenfone
- Picker Mode - handle Intent.ACTION_PICK to select files from other app
- Ensure copy files task won't be interrupted - Add foreground service to prevent task be killed
- Managing file system (Internal storage, SD card) by Media Provider
- Performance improved
- Category: manage multi-thread to avoid serial thread blocked
- ListView: using Asynctask to load data from media provider in getView() to achieve 60 fps
- Counting files: modify SQLite grammar to speed up counting
- Refactor
- Avoid new threads repeatedly by using AsyncTaskLoader with strategy pattern to load files
- Porting with Android Q, R: refactor many functions with unit test to ensure the consistency
- Handle multiple mimeType when opening files
- Applying ZenUI style with custom layout and custom view
- HomePage (Category table layout, storage list, tool table), Storage Analyzer (CardView, animation) and Custom Permission Dialog
- HomePage (Category table layout, storage list, tool table), Storage Analyzer (CardView, animation) and Custom Permission Dialog
Developing and maintaining photos and videos viewing app in Zenfone
- Train UserProfile model (age & gender estimator) by mobileNet with Transfer Learning and integrate to ASUS Gallery
- Allow other app query our inferred result by query content provider of UserProfile
- Offer parameters to retouch photos
Developing SDK of providing main function of ROG Phone (adjust FPS, speed up CPU performance, Aura Lighting, etc) and controlling ROG accessories for Unity developer
- ROG Phone SDK
- Handle Input Event (Key, Motion) to customize ROG Kunai Gamepad controls
