• Designed and created Partner Portal and redesigned legacy webpages with Page UI, the company's newest experimental React.js based internal development tool. Performed end-to-end testing on Partner Portal.

• Worked closely with the team on the design, testing, and deployment of Merchant Experience 3.0 (MEP 3.0), the latest merchant user experience (UI and functionality) update.

• Onboard Page UI to the MEP 3.0 codebase with adjustment to middleware (Node.js) logic to support server-side rendering.

• Transferred the code base of Orbis Colmex Pro, a stock trading mobile app, from Xamarin to .NET MAUI (Multi-platform App UI) development framework (XAML and C#).

• Adjusted GUIs and web services to achieve application performance consistency between iOS and Android on MAUI.

• Redesigned and constructed the frontend interface of Orbis Colmex Pro with Flutter (Dart).

• Evaluated the functionalities (GUIs and visual display, cross-platform consistency, libraries/SDKs), development and compilation environment, and application performance provided by Xamarin, MAUI, and Flutter.

• Conducted tests on different algorithms’ effectiveness in analyzing still and dynamic facial samples captured by IR and RGB cameras of varied qualities and strengths. Enhanced non-liveness recall rate from 93% to 98%.

• Processed >1,000 video samples with test programs and performed statistical analysis on runtime results.

• Worked closely with the algorithm development group to evaluate the performance of algorithms over a diverse set of data, camera parameters, and background OpenCV models.

• Improved the efficiency of testing procedures by optimizing data processing APIs (C++, Python, Shell scripting) and multi-threading setups of existing testing programs/APIs under Linux and Windows environments.
