Brazilian Financial Institution Modernizes Its App with Support from Dink’s Development Team

Context:
The Brazilian financial sector has undergone rapid transformation in recent years, driven by regulatory changes, growing customer expectations, and the widespread adoption of digital banking and investment platforms.

In this context, one of Brazil’s leading financial institutions—offering brokerage and investment services—identified that its mobile app was no longer meeting user expectations in terms of performance, design, and usability.

The institution needed to modernize its app to stay competitive, improve customer engagement, and ensure compliance with the evolving regulatory landscape.

Challenge:
The primary challenge was to completely revamp the mobile app without causing disruption to the institution’s millions of active users.

Key priorities included:

• Enhancing the app’s performance and responsiveness

• Redesigning the user experience (UX) and interface (UI) to align with modern financial apps

• Strengthening data security and compliance with financial regulations

• Guaranteeing service continuity during the transition

• Laying the technical groundwork for future scalability and integrations

Objectives:
To address these goals, the project was led by Dink’s development team, with delivery executed by our engineers and designers based in Brazil.

The team’s objectives included:

• Developing a completely new app with improved architecture and codebase

• Implementing a microservices-based backend to increase scalability and performance

• Introducing a modern, intuitive design focused on user experience

• Strengthening data encryption and security protocols to meet financial industry standards

• Performing extensive testing to ensure a smooth migration with zero downtime for end users

The project followed an agile development model, with close coordination between Dink’s project leads and the client’s internal stakeholders.

Results Achieved:

• The app’s rating on major app stores increased from 3.5 to 4.6, showing clear user approval of the changes

• The Android app’s download size was reduced by over 75%, making installation faster and easier for users

• Data security enhancements were successfully audited by an independent cybersecurity firm

• Users praised the app’s new interface, noting improvements in speed, navigation, and visual appeal

• The app is now prepared for seamless integration with new digital products planned by the institution

Project Challenges:
One of the main challenges arose during the design validation phase. While the initial design proposals were appreciated internally at Dink, early user testing revealed that some elements didn’t fully align with customer expectations.

By applying iterative design sprints and involving both end-users and client teams throughout the process, the Dink team quickly adjusted the visual identity and interaction flows—resulting in a final product that met business objectives and delighted users.

Conclusion:
This project illustrates Dink’s capacity to deliver complex digital transformation projects with speed and quality, leveraging our experienced Brazilian development team.

By combining deep technical expertise with a user-centered design approach, we helped one of Brazil’s top financial institutions modernize its app—enhancing performance, security, and user satisfaction.
