The company boasted various brands, each with its dedicated website. These websites offered a wealth of information, including brand introductions, financing options, methods for applying for loans, and more. They are also the sources of data collection.

We transitioned the technology stack from JSP to Spring Boot and enhanced the web page design. Initially, the application was a standalone unit without a clear separation between frontend and backend components. This service interacted with various API providers, such as Global Payment, offering services ranging from selling .hk domain names to domain name management.

This was a new function within the system that integrated with the Global Payment API Service, facilitating both single and recurring payments. This integration allowed us to offer a domain name auto-renewal service.
