Project Overview
Led the complete digital transformation of a New Zealand trailer rental company, converting their manual paper-based operations into a modern, scalable digital platform. The solution manages over 1,000 trailers across 20+ petrol station locations, processing hundreds of daily bookings while eliminating revenue leakage and operational inefficiencies.
Timeline: 6 months | Team Size: 8 members | Role: Technical Lead & Full-Stack Developer
The Business Challenge
The client’s traditional paper-based system was causing significant operational and financial pain:
- Revenue Loss: Manual paperwork errors leading to lost bookings and untracked rentals
- Equipment Downtime: Poor maintenance scheduling causing trailer unavailability
- Asset Visibility: No tracking system for overdue returns or overnight holdings across remote locations
- Operational Blindness: Zero real-time visibility into performance across 20+ sites
- Infrastructure Costs: Initial proposals required expensive custom kiosks at each location
The Solution Architecture
Multi-Platform Digital Ecosystem
I designed and led development of three integrated applications serving different user needs:
Smart KIOSK Application (React Native)
Innovation: Transformed standard Android tablets into cost-effective self-service kiosks
- Self-service booking management reducing customer wait times
- Cross-platform deployment flexibility across diverse petrol station environments
- Offline-first architecture ensuring operation during connectivity issues
- Microsoft Intune integration for remote device monitoring and management
Operations Management Portal (React)
Full operational command and control dashboard
- Real-time fleet management across 1,000+ trailers and 20+ locations
- Automated maintenance scheduling with proactive service notifications
- Overdue tracking system with automated customer communications
- Comprehensive analytics and reporting for business intelligence
- Role-based access control for different operational levels
Partner Portal (React)
Streamlined interface for petrol station partners
- Location-specific trailer inventory management
- Real-time data synchronization ensuring accuracy across the network
- Simplified workflows for non-technical staff
