Business Challenge
Project Recovery After Delays
The client faced a critical delay after the initial development team failed to deliver tangible results for two months. Elinext was brought in to take over the project, rebuild momentum, and deliver an integration with SSO for the client using Electron.js within just three days.
Tight Development Deadlines
The project had to be completed in a short timeframe, requiring rapid onboarding, clear task prioritization, and efficient collaboration between frontend, QA testing services, and product teams.
Performance and Responsiveness Issues
The document processing software needed significant optimization to handle large document sets quickly and provide a smooth, responsive interface. Enhancing user experience under heavy data loads was a key business priority.
Quality Assurance Under Time Pressure
Despite the tight schedule for document processing app development, maintaining product quality was essential. The team had to achieve high test coverage (unit, integration, and e2e) to ensure the application’s stability and reliability at launch.
Sustained Product Growth and Maintenance
Beyond the initial delivery of document processing software, the client required a reliable long-term partner capable of supporting, improving, and expanding the platform through future versions, ensuring consistent performance, customer satisfaction, and scalability.
Continuous Feature Expansion
As the application matured, new functionality requests from product owners emerged. The challenge was to integrate these features seamlessly without disrupting the stability of the existing product ecosystem.
