Message

At BOX+DICE(AU), I led the migration of the React Native application to the latest release and from JavaScript to TypeScript. I also designed and implemented an N-layered architecture to improve maintainability, stability, and testability.

I introduced unit test coverage, replaced deprecated libraries, and implemented product features based on business and user requirements. I also managed app builds, releases, and deployments to the Google Play Store and Apple App Store.

Earlier, I led React Native and React.js frontend work at YONDU INC., including the Bus Information System and Project Dave. At UNEXUS MEDICAL SOLUTION, I led the migration of a native Android application to React Native for deployment across Android and iOS.
