Case study > Public > Edge One Solutions for Cosafe

About the client
Cosafe is a modern, multi-platform application designed to support organizations in managing crisis situations and improving communication during emergencies. The system was built for broad use - from educational institutions and public sector organizations to commercial enterprises. Thanks to real-time operation, Cosafe enables rapid dissemination of critical information, coordination of response efforts and prevention of threat escalation.
One of the main challenges was transforming the legacy backend layer, originally developed in ASP.NET, into a modern, modular environment based on Nest.js. This step required careful planning of data migration and ensuring compatibility of the new solutions with existing user interfaces and services.
At the same time, the team is implementing advanced end-to-end testing using Playwright, enabling automated verification of key user flows and the elimination of bugs before deployment. As a result, the application maintains a high level of reliability, even in the most critical scenarios.

- Modernization and upgrade of key application components.
- Improved system performance and scalability.
- Ensuring top-quality operation through test automation.
- Maintaining business continuity in high-risk operational environments.
