About the client
Fideval is an investment fund administrator that aims to bring financial products closer to more people through simple and accessible digital experiences. With Investo, its digital investment platform, the goal was to make access to funds easier, improve the user experience, and support financial growth in an intuitive, autonomous, and secure way.
The challenge
The challenge was to bring the investment offering into a digital environment without losing trust or reliability. This meant translating complex processes into a simple, intuitive, and secure platform for different types of users. It also required building a flexible product that could evolve, validate, and scale as the business grew.
Our solution
To address the project’s challenges, we implemented several key solutions.
Cross-platform architecture
The app was built on a single codebase that runs natively on both iOS and Android. This allowed us to reduce development time and maintain a consistent experience for all users, regardless of device, without compromising performance or visual quality.
Security and session management
We implemented a security layer focused on protecting sensitive financial data. The app includes encryption of data in transit, JWT based authentication managed through HTTP interceptors, and automatic session expiration due to inactivity or maximum session time. These measures help ensure that user information remains protected at all times, in line with financial sector standards.
Analytics and data intelligence
We integrated an analytics ecosystem to better user behavior and continuously improve the application by. Tracking key events, we were able to proactively detecting errors, segmenting users, and visually analyzing in-app behavior allowed us to make data-informed decisions and optimize the experience over time.
Quality assurance and release control
We ensured that each feature met business requirements and was accurately reflected in the final experience. In an agile environment, we aligned criteria and detected inconsistencies between design and implementation. Through manual and automated testing, we maintained quality in every release and reduced risks before production.
Experience design and digital product
We transformed complex financial processes into clear, intuitive, and accessible experiences. We defined key user flows by prioritizing clarity and reducing friction in decision-making. Through continuous iterations and validations, we built a consistent experience that fosterts trust.
Tools and technologies
We carefully selected a modern and reliable technology stack, leveraging the best of cross-platform development and next-generation analytics tools designed for the financial sector.
