• Build bridge by Common Language Infrastructure (CLI) in order to managed clients to call native security component.
• Create a test framework to test security user management component, and then migrate Visual studio C# TestRunner (C# Unit Test).
• Use thread synchronization and object-oriented programming with C++, combining event driven programming, C#, and WPF to add a new feature (called as Multiplanar Clips) on Voyager (Premium Confidential Ultrasound Imaging System), which greatly simplifies the workflow to capture and save 2D and 3D video.
• Find the defect in system design and improve the architecture of state manager to facilitate control panel availability configuration with the architecture improvement.
• Use remote debug to fix 50 system crash defects, including interprocess issues, thread race condition, and different bugs in different domains (process), such as vgrAppUI, vgrUI, USI, APR, DMS, and SIP.
• Go through Change Requirement Specification, Feature Design Specification, User Interface Design Specification, use team track to manage development tasks, follow coding standards and best practices for effective development and reliability.
• Write change set document to elaborate detailed software design, code/implementation, and test case, prepare and conduct code review.
• Go through feature delivery whole process, start from rebase, and then build and package. Once build and package succeed, use Sitool to install voyager software, verify test case and do smoke test, afterwards, do sanity test (automation software test), until development complete by check in codes and merge to the main branch.
