Motivation

The client, one of the largest state-owned banks in Europe, faced a critical issue: their legacy deposit operations system was outdated, lacked essential features, and required major architectural updates. Manual processes and fragmented system components slowed down back-office operations, increased the risk of errors, and made regulatory compliance more complex. They needed a robust, secure, and scalable solution to modernize deposit handling, streamline workflows, and ensure data protection, while allowing employees to focus on higher-value tasks rather than repetitive manual operations.

Main challenges

Challenge 01

Intellectual Property Protection

Ensuring the security of sensitive banking data was critical. Developers worked on dual-PC setups with blocked external ports and restricted devices to prevent data leaks, which slowed development. Azati addressed this by implementing secure workflows, coordinating with the bank’s security team, and providing clear guidelines for safe development, maintaining both compliance and progress.

Challenge 02

Access Restrictions to Infrastructure

Limited access to proprietary banking systems delayed deep understanding of the infrastructure and slowed integration. To overcome this, Azati created structured ticketing processes, prepared detailed documentation, and built isolated test environments, enabling the team to work efficiently while adhering to strict security requirements.

Our approach

Knowledge Transfer and Team Integration

Azati joined the project after the customer’s partner selected our team for its familiarity with the financial industry and proven expertise. We created several demos and participated in a demonstration exhibition, which led to our introduction to the in-house team.

Extensive Documentation and Testing

Clear and comprehensive documentation was crucial due to the distributed nature of the teams. We focused on writing clean code and ensuring that 90% of the code was covered by rigorous functional, unit, integration, code clarity, and security tests.

Agile Methodology

The project was developed according to SCRUM principles, with weekly sprints and two-week demo presentations to the customer. Our engineers participated in daily code reviews and collaborated closely with in-house teams to ensure knowledge sharing and high performance.
