Challenge

DefTalk required urgent technical intervention to stabilise a volatile backend and optimise an expensive, underperforming infrastructure before a critical market launch. The primary challenge was to perform a comprehensive server stabilisation and implement a CI/CD pipeline to accelerate deployment cycles while radically reducing operational burn rates to ensure long-term commercial viability.

OmiSoft’s Solution

Mobile App and Server Stabilisation

We conducted a full technical review and optimisation of DefTalk’s mobile applications and backend servers. Our team restructured the codebase, resolved critical bugs and improved system stability to ensure consistent performance across all platforms.

CI/CD Pipeline Implementation

We implemented a continuous integration and deployment (CI/CD) pipeline, enabling faster and more reliable development cycles. This automation streamlined deployment processes and minimised the risk of human error during updates.

MVP Architecture Execution

We applied an MVP architecture pattern to improve scalability and maintainability. This architectural approach supported future upgrades and facilitated a more modular, testable codebase.

Comprehensive Testing Coverage

We developed and executed a full suite of unit, integration and smoke regression test cases. This ensured that all core functionalities worked as intended and reduced the risk of defects in production.

Performance Monitoring Integration

We integrated tools such as Crashlytics, Firebase Performance Monitoring and Fabric Logger to provide detailed analytics and crash reports. These tools enabled real-time performance tracking and rapid issue resolution.
