Letting a Property

The Challenge

A UK-based property letting platform needed to handle the full rental lifecycle — from property search to payment processing — with compliance for Open Banking regulations and support for multiple user roles (Landlords, Tenants, Admins).

My Role

Full-stack developer responsible for:

• Advanced property search with PostGIS geo-location queries
• Payment integration (Stripe, Open Banking, Direct Banking)
• Multi-role authorization system with Laravel Sanctum
• Admin panel with Filament

Technical Highlights

Geo-Location Property Search

Built advanced property search using PostgreSQL PostGIS extension:

• Radius-based searches ("properties within 5km of this location")
• Availability filters with paginated listing APIs
• Supporting thousands of concurrent searches

Triple Payment Integration

Integrated three payment methods:

• Stripe for card payments
• Open Banking API for direct bank transfers
• Direct Banking API as fallback

All payments use webhook signature verification and idempotent Laravel Queue workers to ensure zero double-charges.

Multi-Role RBAC

Implemented with Laravel Sanctum:

• Landlords: Property management, tenant screening, payment tracking
• Tenants: Property search, applications, rent payments
• Admins: Platform oversight, dispute resolution
• Plus: in-app messaging, reviews, and notification pipelines

Key Results

• Advanced geo-search handling thousands of concurrent queries
• Secure payment processing across 3 payment providers
• Complete RBAC system with in-app messaging and notifications
• Active, ongoing production system
