Modernizing for Growth: From Outdated Systems to a Lean, Scalable Stack
Reducing complexity, cutting costs, and accelerating delivery through cloud-native modernization.
Elaborate on the Challenge
Aging technology and fragmented integration architecture held back an enterprise mortgage services platform. The front end relied on a legacy stack built with Classic ASP and MVC, resulting in ongoing scalability, performance, and maintenance challenges. Simultaneously, MuleSoft APIs—structured with distinct Service and Experience layers—added unnecessary complexity and inflated operational costs. The system was no longer fit for lightweight workflows or fast-paced delivery. A transformation was needed to reduce overhead, modernize development practices, and streamline architecture and support.
Objective Summary
To modernize a legacy mortgage servicing application by migrating to .NET Core, re-platforming MuleSoft APIs to Azure Logic Apps, and simplifying integration layers to improve performance, reduce cost, and accelerate change delivery.
Business Impact
Achieved significant efficiency gains and cost savings by modernizing with Azure Logic Apps and .NET Core—cutting costs by over 60%, boosting performance by 50%, and accelerating deployments and development cycles across the board.

Solution - Where smart automation meets AI-ready scale.
Moder deployed a 12-member transformation team to redesign and re-platform the client's application and integration ecosystem. The MuleSoft APIs were migrated to Azure Logic Apps, unlocking the benefits of a serverless, low-code platform tailored for lightweight and scalable workflows. This move alone cut integration complexity and operational costs substantially.
In parallel, the legacy front end was reengineered using .NET Core, introducing modern development standards, improved cross-platform compatibility, and performance optimization. The team further simplified the integration architecture by removing the Service layer and enabling the Experience layer to support both UI and backend communications—significantly reducing redundant maintenance and streamlining future updates.
