About the project
Čavkunović BP is a company from Bihać that operates a network of fuel stations, a restaurant, a motel and residential properties. The goal was to build a complete digital system that brings these business activities together on one platform without relying on an off-the-shelf CMS.
System architecture
The platform is divided into three layers that share the same database:
- Public website — a marketing site with news, services, galleries and contact information.
- Customer portal — registration, shop orders, motel reservations, a Klub+ loyalty card with QR code and job applications.
- Admin CMS — email PIN two-factor authentication, a dashboard for pending actions and more than eighteen management modules.
Key modules
- News management with TinyMCE and automated Facebook publishing.
- Business units for fuel, restaurant, motel and car wash locations with GPS coordinates and Google Maps integration.
- Fuel prices by station with change history.
- Motel room and reservation management.
- Real-estate listings, apartments and PDF catalogues.
- Shop orders, email notifications and customer account features.
- Klub+ loyalty cards with QR and Apple Wallet support.
- Careers module with CV upload and application status tracking.
Security and maintainability
The system uses prepared PDO queries, CSRF protection, controlled file uploads, two-factor authentication and a configurable hidden administration URL. The codebase was designed for long-term maintenance on a practical hosting environment.
Result
The result is a unified web platform that supports public presentation, customer services and daily administration from one secure system.
