Our client operates a marketplace where users can compare personalized, prequalified rates and quotes from multiple lenders and carriers across various financial products, including student loans, mortgages, personal loans, and insurance.

The platform revolves around a Rules Engine that evaluates lenders’ suitability to provide funds. Upon assessment, users are presented with a dashboard displaying available products and loans.

Optimizing user registration and single sign-on features to leverage AWS services has enhanced system functionality and performance. The introduction of a custom A/B testing solution provides increased flexibility for business and data analysis. Moreover, robust integrations with third-party services and credit bureaus ensure seamless user experiences.

Digitizing mortgage 1003 paperwork and streamlining document upload and sign-off processes have simplified operations and reduced manual effort. Seamless integration with Salesforce for back-office operations and the establishment of continuous integration processes further enhance operational efficiency.
