The Cartos Challenge

Cartos’ main objective is to promote the democratization and expansion of access to credit, providing high quality services in all aspects of financial operations. In partnership with Luby, it has played a crucial role in the creation and implementation of new banking as a service financial solutions for the bank.

The Luby solutions integrated into this project:

Financial Innovation

Our first challenge was to assess the application and rebuild it from the ground up based on the issues identified. With a well-defined roadmap for the hybrid application, we organized our operation into four multi-disciplinary teams consisting of back-end, front-end and mobile developers, QAs, POs, Scrum Master, Solution Architect and UX/UI designers.

We started development by working on the architecture of the solution, with the client’s premise being a scalable application with high availability, fault tolerance, and low infrastructure maintenance. We decided to develop a microservices architecture and use AWS Serverless.

In this first version of the application, we also achieved:
  • Integration with SPB (Brazilian Payment System).
  • Integration with SPI (Instant Payment System).
  • Integration with PSTI (Information Technology Service Providers).
  • In addition, the application initially included the basic structure of Internet Banking for essential operations.
The result was a secure system with streamlined processes for opening accounts, banking and tracking accounts through both mobile and web applications, enabling Cartos to provide quality banking services.

Banking Evolution

Digital Account Project
With the initial release validated and a solid roadmap for new features, we worked with Cartos to evolve their core banking system, helping to organize and prioritize the project backlog. Several key integrations were required at this stage, such as

  • Integration with CADOC (Central Bank of Brazil’s Document Catalog).
  • Integration with CCS (Customer Registry of the National Financial System).
  • Integration with NPC (New Billing Platform) for the generation, issuance and payment of bank slips.
  • Over time, new features were developed, including batch transaction remittance and fee control.
Banking as a Service Project
We also developed the Banking as a Service project, a milestone in the bank’s history. With a team specialized in the financial sector, we provided Cartos with all the APIs for both digital accounts and CCB issuance, along with a back-office platform designed specifically for operational control.

Cartos’ Banking as a Service is aimed at lenders, such as corporates, fintechs and bank correspondents, as well as the capital market, including FIDCs, securitization companies and assets.

Cybersecurity

Our team also led cybersecurity projects for the bank. We enabled KYC (Know Your Customer) tools through integration with five technologies and assisted in establishing the security action flow.

In partnership with Cartos and Luby, a payment gateway was developed and integrated with a security and anti-fraud tool.

Payment solutions

As briefly mentioned above, a payment gateway was developed, providing inventory control and order history. Payment solutions for e-commerce have been integrated: Pagseguro and Movingpay.

Our team, with strong expertise in payment development integration, delivered the project quickly and securely, allowing Cartos to begin operations on the Merchant Dashboard project.
