Could you build this?
No The scoring logic is simple, but a real version must run inside a bank or lender's payment switch with NPCI/UPI integration and low-latency production guarantees. It also needs fraud-domain tuning on real transaction data that an outside builder won't have.
What it would actually take: The core is a low-latency rules and scoring service (likely Go, Rust, or Java) with a streaming feed of UPI transactions and credit-line state. Making it production-grade requires payment-switch integration, banking regulatory compliance, and historical fraud and repayment data to calibrate the thresholds. Those data and integration relationships are what separate a demo from a deployable product.
