Qualica is an investment and technology company focused on building and scaling businesses in the financial services and technology sectors. Rather than acting as a passive investor, Qualica takes an active role in shaping the growth of its portfolio companies, combining capital investment with hands-on strategic and operational support.

Backed by a team of experienced entrepreneurs and technologists with decades of industry experience, Qualica works closely with its companies to accelerate product development, strengthen technology foundations and drive sustainable, long-term growth. Its portfolio spans multiple stages of maturity and includes digital platforms and software products designed to solve complex, real-world business challenges across different markets.

We had to find a way to maintain the utmost security in the digital banking platform, while providing enough flexibility for different banking processes. Often this involved approaching things differently and finding the common thread that was true for all banks.

For instance, banks have many ways of saving your account information and showing you your current balance. But the logic at the core of every bank account works in the same way: your current balance is the sum of a series of events.

We worked with Qualica on the implementation of an event-sourced system that could reflect common states based on the sum of events up to that point – a neat, elegant solution that can work asynchronously, eliminating locking and volume issues.

A cloud-capable transaction, saving and lending core

In sync with their team, we helped Qualica build a single, cloud-capable, API-based core that handles transactions, saving, and lending – the essential parts of any banking service. This includes more than 30 supporting services such as decisioning, workflow, document management, financial ledger, and product configuration.

Working with Qualica’s team on developing a unique software architecture

While the client’s team developed software architecture and built strong foundations for it, we helped them get the most out of it. We extended their in-house software development team, helping the client constantly add new features and functionalities and ensuring that the platform meets the requirements of diverse end clients. The architecture development process involved creating new microservices and upgrading existing ones.

• Backend services are written in Java 11 and Spring Boot
• The front-end is built with Angular
• MariaDB is used as the main database in most of the services, as well as the event store
• For streaming events, we are using Kafka
• For Saga orchestrating, we are using Camunda
• Keycloak – identity service
• DevOps technologies – Docker, Kubernetes, OpenShift, Jenkins
