What is the Back-Office Portal?

The Back-Office Portal provides essential administrative capabilities for banks participating in the Open Finance platform. It’s the control center where bank staff manage customer consents, monitor API usage, and ensure compliance.

​
Core Back-Office Capabilities

  • Monitor active consents and their expiration dates
  • Revoke or update consent permissions
  • Maintain complete audit trails for regulatory compliance
📊 Dashboard & Monitoring
  • Real-time view of API usage across the bank’s Open Finance services
  • Monitor customer consent status and data sharing activity
  • Track which third-party providers (TPPs) are accessing customer data
  • Generate compliance and usage reports
👥 User Administration
  • Manage bank staff access to the back-office system
  • Handle customer account queries and support requests
  • View customer consent history and data access logs
  • Administrative controls for consent management
⚖️ Compliance & Audit
  • Complete audit trail of all consent changes
  • GDPR-compliant consent workflows
  • Regulatory reporting capabilities
  • Data access logging for compliance reviews

​
Built with Agentic Coding

This entire portal was built using Claude Code - demonstrating how AI-assisted development accelerates building complex financial applications.

​
How It Was Built

Starting Materials:
  • Open Finance API documentation (publicly available)
  • OpenAPI specifications for consent management
  • Standard web development stack (React, Node.js, TypeScript)
  • Claude Code for AI-assisted development
Development Approach:
  1. AI-Generated Architecture - Claude Code helped design the system architecture
  2. OpenAPI-Driven Development - API client code generated from specifications
  3. Rapid Prototyping - Core features built in days, not weeks
  4. Best Practices Built-In - Security, error handling, and validation from the start

​
Technical Stack

Frontend: React 18 + TypeScript + Tailwind CSS
Backend: Node.js + Express
Database: PostgreSQL
Real-time: WebSocket for live updates
Caching: Redis for performance
Deployment: Render.com (production-ready)

​
Key Features Implemented

Real-time Updates
  • WebSocket connections for instant consent status changes
  • Live API usage monitoring
  • Dynamic dashboard charts and metrics
Security First
  • OAuth 2.0 integration with Open Finance APIs
  • Industry-standard authentication and encryption
  • Input validation and sanitization
  • Comprehensive audit logging
Performance Optimized
  • Redis caching for API responses
  • Efficient database queries with proper indexing
  • Progressive loading for large datasets
  • CDN-optimized static assets
