Plaid-verified income
The Challenge
Underwriting ran on paystubs, PDFs, and phone calls.
Every applicant meant chasing documents, eyeballing income, and waiting days for a decision. Manual review was slow, inconsistent, and didn't scale with the dealer pipeline — costing approvals.
What We Built
A Plaid-powered verification flow.
Applicants connect their bank through Plaid Link in minutes. The platform supports income report requests through Email or SMS and gives administrators clear Income Reports and Income Summaries for review.

Security and infrastructure.
Capital Auto Loan needed more than a polished Plaid integration. The platform was built with strict separation, encryption, monitoring, and minimal data storage from the start.
Security was treated as a core product requirement, not an afterthought. Every layer was designed to reduce exposure, protect sensitive financial data, and give Capital Auto Loan a system they could trust in daily operations.
Only Capital Auto Loan administrators can access the data, and the application stores the minimum information necessary to reduce risk while still supporting underwriting review.
Application stack
Built with Next.js, TypeScript, and Tailwind CSS for a modern, reliable, and maintainable web application.
AWS infrastructure
Hosted on an AWS EC2 server instance, with generated income report PDFs uploaded securely to an AWS S3 bucket.
Isolated containers
Orchestrated with Docker containers so application services stay separated and easier to control.
PostgreSQL backups
Backed by a PostgreSQL database with daily database backups to support recovery and operational continuity.
Double encryption
Sensitive data is protected in transit and at rest, reducing exposure across storage and transmission paths.
Monitoring and access control
Sentry and AWS CloudWatch Logs support visibility, while access is limited to Capital Auto Loan administrators.
