Build a Fraud Detection & Prevention Platform with AI - in Hours

ProjectCode generates a complete, production-ready Fraud Detection & Prevention Platform from a single natural language prompt. In hours instead of months, you get a React frontend, NestJS REST API, PostgreSQL database, and authentication - fully integrated, live-previewed, and deployed to a URL you own.

Estimated build time: 2–4 hours

The Challenge

Why building a Fraud Detection from scratch is hard

Building a Fraud Detection & Prevention Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing fraud detection-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Fraud Detection needs

ProjectCode generates a production-ready Fraud Detection with all the modules your team needs from day one.

Real-time transaction scoring with rule-based engine
Behavioral biometrics and device fingerprinting
Velocity checks: transactions per minute, IP, device
Watchlist and blacklist screening
Case management for flagged transactions
Model feedback loop: label outcomes to retrain
Risk-based step-up authentication triggers
Reporting: fraud rate, false positive rate, saved losses

Architecture

How it's built

The generated Fraud Detection follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for fraud detection workflows

NestJS REST API with dedicated fraud detection modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all fraud detection entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live fraud detection status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Fraud Detection

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

  • transactions (id, user_id, amount, type, ip, device_fingerprint, merchant, country, timestamp, risk_score, decision)
  • fraud_rules (id, name, conditions jsonb, action, priority, is_active, workspace_id)
  • fraud_cases (id, transaction_id, risk_score, signals jsonb, status, analyst_id, label, resolved_at)
  • watchlists (id, name, type, entries jsonb, is_active, workspace_id)

FAQ

Common questions about building a Fraud Detection

The rule engine is optimized for sub-100ms response time. Rules are loaded into memory and evaluated in-process. Complex ML scoring runs asynchronously and updates the risk score within 500ms.
