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
