The Challenge

We had the great challenge of achieving a modular and scalable design, and a system that would manage the content of the four banks, in an easy and flexible way, building a library of components to cover the needs of all products and services.

It was challenging to create a graphic system that allows scalability and application in all four banks. Working together with teams from different areas of the Petersen Group was key to understand different points of view on problems and allowed us to explore possible solutions to generate an intuitive product that reflects the needs of both the business and its users

The results

  1. We improved up to 50% the loading and navigation speed through Server Side Rendering and different optimization practices.

  2. Fast and agile process of modification, approval and publication of content through a headless CMS such as Contentful.

  3. To achieve a hierarchical visualization of all the products offered by the bank, components were designed to show the relevant information to the user in an attractive way.
