Enterprise Platform Modernization: Migrating to React and Architectural Enhancements

The client’s existing enterprise platform, developed over 10+ years using Angular, has become difficult to maintain due to inconsistent toolsets, custom workarounds, tightly coupled UI and business logic, and architecture issues that hinder feature development and performance. Additionally, the system's licensing is not aligned with current functionalities, requiring manual workarounds, and backend response times are slowed by outdated SQL query mechanisms. These factors lead to delayed releases, unstable performance, and limited ability to incorporate user feedback rapidly.

• Accelerate development cycles and improve stability to enable more frequent feature releases.
• Transform the system architecture by migrating the frontend to React, implementing microservices, and decoupling business logic from the UI.
• Improve UI component consistency, add new components, and ensure smooth integration between legacy and new modules.
• Upgrade database querying mechanisms to reduce backend response times by 10-20%.
• Achieve full licensing coverage of current functionalities, eliminating manual workarounds.
• Enhance system maintainability through code standardization, best practices, and easier framework/library updates.
• Support ongoing feature development such as advanced integrations (e.g., AI/ML capabilities).
• Implement comprehensive testing strategies with integration and regression tests to ensure system stability.

• React-based UI with 20+ UI components, including new and improved elements with validation, routing, and data integrity features.
• API layer to decouple business logic from the UI, supporting microservices architecture.
• Migration of core modules (app builder, authorization, reporting, notification) into dedicated microservices.
• Integration mechanisms to ensure seamless interaction between legacy iframe-based components and new modules.
• Database query optimization techniques to upgrade SQL queries and improve backend response times.
• A licensing framework that accurately reflects the full functionality set, removing manual workarounds.
• Automated testing suites using Cypress for integration and regression testing.

• Legacy systems via iframe or similar integration points
• Database systems for optimized queries
• Third-party licensing and authentication services
• Notification and reporting services

• Backend response times reduced by at least 10-20% for critical SQL queries
• System should support more frequent release cycles with minimal downtime
• Codebase standardized to reduce duplicate and inconsistent code by 20+ UI components
• Ensure seamless interaction between legacy and new components to avoid data loss
• Automatically cover major system functionalities with regression and integration tests

Successful migration and architectural enhancements will enable faster development cycles, increased system stability, and improved user experience. Backend performance will be significantly improved, with response times reduced by 10-20%, facilitating real-time processes and better user satisfaction. The consolidated licensing framework will eliminate manual workarounds, ensuring full feature coverage. Overall, the platform will become more maintainable, scalable, and ready for ongoing innovation, supporting the client’s growth and ability to incorporate user feedback more rapidly.
