Modernizing a legacy claims management platform.
An incremental modernization of operational insurance software—separating tightly coupled workflows into a platform that could be changed with greater confidence.
01 // CHALLENGE
Critical operations constrained by an aging application.
The PHP and jQuery system combined interface concerns, business rules and operational workflows. Authentication limitations, database evolution and manual processes made routine changes difficult to introduce safely.
02 // APPROACH
Modernize the system around stable boundaries.
Business logic was progressively separated behind a Spring Boot API while Angular provided a component-based interface for role-specific workflows. This allowed critical areas to evolve without requiring a disruptive full rewrite.
03 // ARCHITECTURE
From coupled application to separable platform.
Authentication, domain behavior and data evolution become explicit platform concerns instead of remaining embedded in the legacy interface.

04 // ENGINEERING WORK
Changes across the full system boundary.

05 // OUTCOME
A maintainable foundation for continued evolution.
The modernization created clearer architectural boundaries, separated the frontend from core business logic, established a modern access-control model and made future changes safer to deliver incrementally.
