Legacy Claims Processing Modernization

The client operated a mission-critical claims processing system used daily to review, validate, and finalize claims. Over time it became deeply embedded in workflows and connected to many upstream and downstream systems.

The platform had grown organically for over a decade into a tightly coupled, monolithic system with heavy reliance on stored procedures and no shared services. Enhancements required code-level changes, which slowed releases and added risk. The lack of modularity limited reuse and modern cloud practices, and performance suffered as data volumes grew.

Winning Edge architects and engineers designed and implemented a modernization roadmap centered on microservices. The team decomposed the monolith into independent, event-driven services communicating asynchronously through APIs. Using serverless technologies on AWS, the new platform gained elasticity, modularity, and cost efficiency, with loose coupling, automated deployments, and reusable components.

The modernized platform now runs as flexible serverless microservices, with much better scalability and reliability. Maintenance cycles are shorter, features ship faster, and integration with other enterprise systems is seamless. AWS reduced operating costs while handling spikes in claim volume without performance loss.
