Node.js/.NET Banking Platform

I have laid out the core of an online banking platform and now need an experienced developer who can pick it up in either Node.js or .NET, build it out cleanly, and keep the codebase future-proof. The application will be customer-facing only, so every screen and service you create must be intuitive, fast, and rock-solid.

The immediate scope covers three pillars: full account management (opening, closing, balance queries, profile editing); real-time transaction processing (internal transfers, external ACH, payment history); and loan management, including application intake, amortization schedule generation, and repayment tracking. Security is non-negotiable: two-factor authentication, end-to-end encryption for data at rest and in transit, and automated fraud-detection hooks must be baked into the workflow from day one.

Please structure the work so that I can see well-defined modules and clear API contracts. Postman collections or Swagger docs for every endpoint, concise README instructions, and unit tests that cover the critical paths are expected alongside the source code in Git. Once those are in place, I’ll handle UI polishing and infrastructure deployment.
