The Challenge

App Reconstruction01

Credicomer already had a monolithic application. Our team had to reconstruct all of its current functionality under a new architecture. Adding new features for easier customer transactions and acquisitions of banking products online.


It became a necessity to update the infrastructure with the latest technology — Our team had to build a high-availability on-premise product with improved functionalities and an improved user experience.

Time & Quality03

As banking institutions are in a race for technological innovation, Credicomer needed to launch its new products in the least amount of time possible and with high-quality results to stay as one of the top banking institutions in El Salvador.

Sustainable solutions

Elaniin's working model involves Agile's good practices, involving Credicomer's representatives through each stage of the process to ensure strategic alignment. We created a scalable, trusted, and sustainable solution for the client to manage on its own, as the last platform was a closed tool maintained by an external provider.

Developers’ main takeaways

  1. We focused the creation of the MVP on quickly stabilizing the product and making essential adjustments to its usability to maximize the delivered value within the designated time.
  2. The constant communication and collaboration established with the client were key to delivering a valuable product that solved its needs and exceeded expectations.
  3. Each member of the Team Augmentation service was carefully chosen for their high performance and skills profile to solve each of the project's challenges.

  2. A complete upgrade of web and mobile online banking has been made possible with Credicomer Online. Thanks to world-class technologies and the implementation of a software architecture that enables scalability and high availability undoubtedly distinguishes this banking platform.
