Business Challenge
Connecting dozens of legacy property databases with modern banking APIs was creating data fragmentation and security risks. The lack of a unified middleware engine was slowing down loan approvals.
Our Solution
We built a specialized Node.js middleware layer with high-integrity data validation and automated error recovery. This unified engine synchronized credit checks, property valuations, and user identity across 15+ external systems.
Strategic Impact
Mortgage approval turnaround time reduced from 3 days to 4 hours.
Operational errors due to data fragmentation dropped to 0%.
