Development and Implementation of a Modern Credit Simulator for a Leading Romanian Bank

The project involved developing a Corporate Credit Simulator for a leading Romanian bank, aiming to enhance the credit assessment process for corporate clients. The bank’s existing tool, an Excel-based application, was outdated, difficult to use, and lacked integration capabilities with the bank’s existing systems. The tool’s limitations included a lack of user-friendliness and an inability to support a structured pricing approval workflow. Additionally, only one individual had comprehensive knowledge of the tool, and there was no existing documentation, posing a significant risk to the continuity of the process.

The primary challenge was replacing the old Excel-based tool with a more robust, integrated application. The bank needed a system that was not only user-friendly but also capable of integrating seamlessly with their current systems to facilitate a pricing approval flow. The absence of comprehensive documentation and reliance on a single person for knowledge transfer further complicated the transition. This scenario posed risks related to knowledge continuity and operational efficiency.

To address these challenges, the project focused on developing a new application built on modern, scalable technologies. The solution aimed to:

The development of the Corporate Credit Simulator utilized a robust tech stack to ensure reliability, scalability, and ease of maintenance:

• Backend Development: The backend was developed using the Spring Boot framework, a popular Java-based framework known for building microservices and robust APIs. This choice facilitated the creation of a flexible, secure, and efficient backend system.
• API Specifications: The application employed Swagger specifications, defined in Swagger/OpenAPI YAML, to design and document the APIs. This ensured clarity and consistency in API development, making it easier for developers and stakeholders to understand the application’s API architecture.
• Frontend Development: The frontend was built using Angular 14, a modern web application framework. Angular’s component-based architecture provided a modular, maintainable, and dynamic user interface.
• Build and Source Management Tools: The project used Jenkins and GitLab for continuous integration and continuous deployment (CI/CD), enabling automated builds, testing, and deployments. This setup improved development efficiency and reduced the time to market.
• Data Access: PostgreSQL, a powerful open-source relational database, was used for data storage. Its robust performance and scalability made it an ideal choice for handling the bank’s data requirements.
• Runtime Platform: The application was deployed on RedHat OpenShift, a Kubernetes-based platform that provides a secure and scalable environment for running the application.

The project was executed by the Synergo Group, comprising a multidisciplinary team of experts:

• Tech Lead: Led the technical strategy, architecture, and overall execution of the project.
• 2 Backend Developers: Focused on building and maintaining the backend APIs and services, ensuring robust and scalable server-side functionality.
• 2 Frontend Developers: Responsible for the user interface, implementing a responsive and intuitive design that facilitated a seamless user experience.
• 1 Business Analyst: Worked closely with the bank’s stakeholders to gather requirements, define business processes, and ensure that the developed solution met all functional and non-functional requirements.

The team’s collaborative effort ensured the successful delivery of a comprehensive and integrated solution that met the bank’s needs for a modern, efficient, and user-friendly Corporate Credit Simulator.
