Finbricks. Multibanking with clear data visualization and intuitive back-office tools.
Overview
- Intuitive UX/UI across all applications
- Clear and accessible data visualizations
- Innovative demos of fintech services
Finbricks provides a showcase multibanking application and a demo version of the Whitebricks payment gateway. The platform is built on a custom backend and supports dedicated back-office applications with a shared frontend framework. These include the Admin Console for client management and the Merchant Portal for merchants using Finbricks services.
Both demo applications allow potential clients to explore the main product, test the payment gateway and provide early feedback.
Business challenges
- Inability to visually demonstrate functionality to clients
- The need for interactive demo applications to support business
- Lack of a tool for market validation and feedback collection
Finbricks couldn’t easily demonstrate the functionality of their solution to potential customers. Although they had a quality backend with innovative features, they lacked a modern frontend.
This absence of representative tools fundamentally limited the business potential and hindered the expansion of their services in the market.
Design challenges
- Lack of UX/UI competencies in the original development team
- The need for an intuitive interface for complex banking operations
- The need for a consistent visual style across applications
The original interface was created in collaboration between internal and external developers without specialized UX/UI skills. This led to complications not only in the visualization of key functions. The main goal was to provide services in the form of redesign, UX/UI improvements, and frontend implementation.
The work consisted of developing the frontend of the Whitebricks demo payment gateway and the Multibank sample application, including the conversion of all key features into a modern interface. This is what makes the platform easy to use and fully prepared for future growth.
Technological challenges
- Complicated integration to specific Finbricks API
- The need for expert data flow optimization for frontend needs
- Lack of technological foundation for scaling
The main technological challenge was integration with the specific Finbricks API, where the data structure from the backend often did not match the requirements for proper frontend display.
This is where we utilized the expertise of our frontend and UX team, technical knowledge of architecture, and close cooperation with the backend team and the client’s product owner.
How we proceeded
- In-depth analysis of API and data structures before starting development
- Close cooperation between UX/UI designers and the client's development team
- Iterative development of a comprehensive multi-bank portal
The collaboration was based on a close connection between our UX and development team and the client’s Product Owner. It was not just about ensuring a clear, intuitive environment with ease of use for all applications. It was a comprehensive process starting with an analysis of the API and data flows.
We then iteratively designed and developed individual digital products. The Whitebricks frontend application, which serves to demonstrate PSD2 payments, and then the Multibank sample application, which clearly visualizes data. This approach also enabled continuous functionality verification.
The solution was to develop a modern frontend for two key applications – Whitebricks and Multibank. These are now used by the sales team to present services and collect feedback.
Technologies used:
React
TypeScript
TailwindCSS
MUIVite
TanstackShadcn/UIOur solution
Work began with the demo frontend for Whitebricks which allows potential clients to see how a real payment flow operates.
Next came the redesigned multibanking frontend that demonstrates how the future merchant-facing product could look. The interface includes all key features such as cashflow and balance visualizations, frequent counterparties and detailed transaction filtering.
Each application required a redesign, UX improvements, frontend implementation and careful API integration. Close collaboration between our frontend and UX teams, the client’s Product Owner and the backend team ensured smooth data flow and resolved API inconsistencies.
- Whitebricks payment gateway frontend: real-time PSD2 payment demo
- Frontend Multibank application: clear visualization of key functions
- Connection to Finbricks API: optimization of data structure in accordance with the frontend
Impact
- Innovative platform with a unified and modern frontend
- Representative demos of Whitebricks and Multibank applications
- Consistent UX/UI with a stable technological foundation
The result is a cohesive fintech platform with a modern and consistent interface. Users gain a clear overview of accounts and transactions, while administrators benefit from an efficient management environment.
Thanks to the unified UX/UI and scalable architecture, the platform is easy to use today and ready to evolve along with the client’s needs.
Argo22 completely covered the design and implementation of frontend solutions for us. From start to finish, they handled the entire process with great professionalism, and the resulting services look great. Modern, clear and user-friendly. We greatly appreciate their expertise, reliability and the helpful approach of the entire team. We can fully rely on Argo in matters of frontend development and we rate the cooperation as absolutely excellent.Key findings
- A high-quality visual layer is a prerequisite for B2B technology sales
- Frontend and backend must cooperate already during the design of the data architecture
- A functional demo builds trust faster than technical documentation
Experience confirms that even the best backend solution is abstract to the customer until it takes on a concrete visual form. Creating demo applications transformed the “invisible” technology into a tangible business tool that builds trust almost immediately.
Instead of selling visions, the client now has a functional tool in their hands, thanks to which they receive valuable feedback directly from potential customers. This approach not only speeds up business negotiations, but also ensures that future versions of the product develop as the market expects.

The key added value is the automation of steps that would otherwise entail a significant administrative burden. The connection was built from the beginning on integrations with internal and external systems (e.g. SAP, EDC, DMS, etc.). The delivery included continuously maintained documentation that unified the tasks across teams and minimized scope creep and communication noise.
The platform was designed from the beginning to handle the gradual expansion of the number of users, the involvement of other entities, and the future development of functionalities in connection with the development of the electricity sharing market.
Approach
- Discovery & MVP framing
- UX/UI & early validation
- Iterative delivery
- UAT & launch readiness
Together with the client, we defined a product strategy, key scenarios and a minimum scope that would allow for rapid validation of the new market.
During the first two months, alpha versions and prototypes were created, which underwent UX testing and set the direction for further development. This took place in sprints with continuous alignment of the product, design and technology teams and parallel preparation of integrations to key systems.
The solution was prepared for verification in a real environment, including setting up processes for long-term operation and further development of the platform.
