PROBLEM

The company’s digital services ecosystem lacked a unified account management portal. Key account functions — such as password management, two-factor authentication, recovery options, and payment settings — were scattered across multiple portals.

As the company’s digital services grew in popularity, fraudulent activities and account theft increased, resulting in a surge of tech support requests.

Additionally, the company had limited insight into its users, making it difficult to personalize experiences or offer targeted upsells. Every digital service required users to re-enter the same information, negatively impacting overall conversion rates and customer satisfaction.

SOLUTION

A centralized user account portal, akin to Google Account, featuring self-service management, enhanced security controls, and user data collection for personalized experiences.

  • An in-house development team 

  • Core team size: 12 people 

  • Overall team line-up: project manager, designer, system architect, system analysts, back-end developers, front-end developers, QA engineers, DevOps engineers, technical writer
