the testing and integration process to achieve Continuous Deployment
from development to production environment. I used Java Spring Boot,
Scala, and Kotlin in the backend, whereas Angular.JS in frontend. To
ensure automated testing, I created a unit test with Mocha, Chai,
Cucumber for frontend, and JUnit, Mockito, for the backend. The app was
shipped as a Docker container and orchestrated on a private cloud to
achieve high scalability and HA. It was the first full Agile project in
Hong Kong entity that disrupted both the Wealth Advisory experience and
