Motivation
The goal was to develop a new version of an online banking platform that included both a web version and a mobile application API. Azati was responsible for developing the web version, including both customer-facing interfaces and server-side logic, and creating the mobile API for the banking platform.
Main challenges
Challenge 01
Workflow and Release Delivery Issues
Initially, the release workflow was poorly organized, and necessary Git permissions were invalid. As the project grew, this became critical. Azati’s involvement helped reorganize the workflow, allowing for timely delivery of results.
#1
Challenge 02
Integration with Third-Party Services
Online banking integrates with various third-party services (e.g., for money transfers to other banks' clients). The team worked proactively with external vendors to understand their services and find optimal integration solutions.
#2
Challenge 03
Performance Issues and Code Quality
The project suffered from poor performance due to unnecessary code and inefficient workflow. Azati helped establish a reliable workflow, refactor outdated classes, eliminate redundant verifications, and introduce automated tests.
#3
Our approach
Agile Project Management with SCRUM
To address workflow issues, Azati introduced SCRUM methodology, shifting the project management to an agile framework that clarified processes and sped up feature delivery.
Monolithic Architecture Solution
The platform was built around a monolithic architecture. Although initially deployed on a single server, the solution was scaled to multiple servers, overcoming session tracking challenges.
API Development and Integration
Azati developed the Web API that interacts with the business logic layer and integrated with internal bank middleware. This solution enabled easy integration with other banking systems and third-party services.
