Built a multi-site parking and gate management SaaS using Laravel 13, React 18, and TypeScript. The Laravel REST API uses Sanctum and Spatie permissions and supports three portals for HQ admins, site operators, and customers. Integrated LPR cameras and TCP-controlled barriers/kiosks for automated vehicle entry and exit. The system also handles live occupancy, season passes, billing, and rewards, with a shared data model keeping customers, vehicles, passes, and parking capacity in sync. Deployed using Docker Compose with automated backups.
