Selected case study
Scaling a Mortgage Servicing Platform
A business-critical servicing platform needed dependable feature delivery, scalable APIs, efficient financial data access, and reliable third-party integrations.
Project context
Understanding the delivery environment
Mortgage servicing software sits at the intersection of financial data, operational workflows, customer activity, and external financial systems. Changes must preserve established business rules while remaining supportable under ongoing production use.
The engagement combined hands-on full-stack delivery with technical leadership across the React interface, .NET APIs, SQL Server data access, and third-party integrations.
Constraints
What the solution had to respect
- Business-critical servicing workflows could not be disrupted during ongoing feature delivery
- Financial calculations and state transitions needed to remain consistent across application layers
- API and database performance had to support growing workflow demand
- Third-party financial integrations required dependable error handling and operational visibility
Technical approach
How the work was approached
- Developed core servicing workflows across the .NET and React application
- Improved API scalability and SQL Server performance
- Integrated third-party financial tools while protecting business rules
- Supported production reliability and ongoing delivery
Outcome
A more maintainable servicing platform with stronger API scalability, database performance, integration reliability, and production readiness.
- Core servicing workflows delivered across the application stack
- API and SQL performance treated as one end-to-end request path
- External integrations isolated behind application-level contracts
- Production reliability considered alongside ongoing feature delivery
