Custom Borrowers Portal and Zoho CRM Integration for LendNow
Lendnow, a lender for businesses of all sizes, faced challenges as borrowers had no portal to check their loan application status. They needed a customer portal for tracking loan progress, a back-office dashboard for managing borrowers, and integration with ZohoCRM. We proposed extending the Dockerized Node.js backend to support these needs, introducing a borrower's portal, a management dashboard, and a staging environment to test new features without disrupting production, thereby reducing the risk of data corruption.
