A Leading Bank Accelerates Its SMB Lending with the Microservice Loan Origination System by Diasoft

March 19, 2024

Diasoft and one of the largest domestic banks completed the migration of the bank’s SMB Loan Origination System to the microservice architecture.

Due to the new-generation architectural approach, the bank now solves its lending business tasks quicker and more effectively. It also allowed the bank to achieve faster TTM and reduce regression risks among other.

The bank offers several credit products tailored for Small and Medium-sized Businesses (SMBs) including business mortgages, instant loans, overdraft facilities, and refinancing options. Each of these products is now supported by a separate application designed to efficiently execute a specific business task. These applications consist of one or several microservices, they are easy to configure and operate independently, which allows quickly changing parameters of credit products without interrupting business processes.

The project scope included end-to-end implementation of the "Business Mortgage" product by the Diasoft team, while other credit products for SMBs were configured by the bank experts on their own, with the help of pre-integrated low-code tools.

The migration to the microservice architecture was supported by the following Digital Q tools and accelerators:

• Digital Q.BPM for design of business processes and rules;
• Digital Q.ProductFactory designed to manage the centralized catalog of credit products / service plans and to ensure launch of new bank products;
• Digital Q.Palette used to set up UI forms.

Diasoft integrated the implemented Loan Origination system with other microservice solutions installed in the bank. The solution was also integrated with a special service that searches for borrowers’ data to automatically fill out respective loan application fields.

The migration of the Loan Origination system to the microservices architecture allowed the bank to quickly make changes in its lending business processes, enhance its customer services, ensure high fault tolerance and performance. The new technology facilitated customization of credit products to market needs. With the use of mature low-code tools provided by the Digital Q platform, all product parameters can be easily adjusted by bank employees without involvement of the vendor. All these benefits will help to strengthen the bank's leading position in the SMB lending market.
