Telecommunication services customer portal
Modernizing a Telecommunication Portal for Enhanced User Experience and Flexibility
Overview:
We developed a state-of-the-art portal for a telecommunication company, enabling end-customers to browse fax messages, call history, invoices, and personal data. Additionally, customers can configure services without contacting the provider, ensuring a seamless and user-friendly experience.
Challenge:
The primary goal was to create a modern, high-performance website while preserving the functionality of an existing decade-old system with a substantial user base. The new portal needed to be faster, more secure, and adaptable for future expansions. A major challenge was the complex and risky process of migrating a legacy database. We had to create a contemporary entity model that interfaced with the outdated database and ensure the user interface was configurable for different resellers’ branding.
Solution:
To overcome these challenges, we implemented the following:
-
Abstraction Layer:
We created an abstraction layer over the legacy database, enabling it to function as if it were a modern, structured database. This allowed for smooth integration without extensive database migration.
- Single Page Application (SPA): We transitioned the front-end architecture from Server Side Rendering (SSR) to a Single Page Application, significantly improving performance and user experience.
- White Labeling: The new application is white-labeled, allowing resellers to customize the user interface with their CSS files and assets. Resellers can also configure which functionalities are available to their end-customers, providing a tailored experience.
- Enhanced Security: We implemented security improvements without altering the existing database tables, ensuring data integrity and protection.
Result:
The modernized portal met all the client’s requirements, resulting in a faster, more secure, and flexible system. Our customer was highly satisfied with the results, leading to extended cooperation to modernize their administration portal for employees and resellers.
