A core real-time reporting application based on Angular 9 with high technical debt, strong architectural coupling, dependency on legacy libraries, and over 180 active security vulnerabilities. The stack compromised performance, scalability, security, and the product’s ability to evolve, making a traditional version migration unfeasible and high-risk.
AI-assisted incremental refactoring starting from a new Angular 20 project, migrating component by component. The approach combined the intensive use of Generative AI to accelerate refactoring, standardize code, and reduce manual effort, with continuous human validation. It included architectural modernization with Standalone Components, Signals, new Control Flow, dependency updates, and style refactoring.
Complete elimination of security vulnerabilities, significant performance gains in real-time rendering, and an expressive reduction in code complexity and coupling. The result was a modern, scalable architecture with greater predictability for future evolutions and the delivery of a new, documented Angular 20 foundation ready to sustain product growth.
