A large bank providing services to millions of users in several countries. The client operates with individuals and legal entities online and through its 400 offline offices.


Our client focuses on using high technologies and an active transition from the offline environment to the online business. This stimulates the need for additional software development teams with unique expertise in finance industry technologies and processes. The client’s business is being scaled up at a high pace, and the bank, therefore, requires flexible professional support from experienced specialists. It was essential for our client to find a reliable partner for a long-term partnership. They needed flexible cooperation options, with specialists joining a project instantly. A wide array of top software developers with an extensive tech stack was also required. Here are the projects that we’ve already completed:

  • development of new features and support of the existing internet banking app

  • working on the functionality of the user’s personal area
  • elaboration of capabilities for account opening by individuals and legal entities
  • development of fundraising options for a user’s specific purposes
  • handling apps for credits, loans, installment payments
