Timeline
June 2025 – April 2026
Total Budget
$9,690+ (including change requests)
The project was delivered across three primary milestones, followed by four post-launch iterations based on evolving requirements and user feedback.
Team Composition
Ropstam assembled a dedicated cross-functional team, including mobile developers, backend engineers, web developers, QA specialists, and project managers, to ensure seamless delivery.
The Challenge
Operating in a city with one of the highest densities of speed cameras, the project required solving both technical and product challenges:
Developing a real-time GPS proximity system with directional awareness and customizable alert distances (50–1,000 ft)
Ensuring consistent alert functionality in iOS background mode under Apple’s strict execution limitations
Maintaining accurate camera data through automated third-party API synchronization
Building a reliable community submission and moderation system
Implementing Apple In-App Purchases with subscription lifecycle handling
Creating a reporting system that quantifies savings from avoided tickets
The Solution
Ropstam delivered a robust, end-to-end ecosystem:
A React Native iOS app with background location tracking, real-time alerts, and configurable user preferences
A React.js admin portal enabling full operational control
A scalable Node.js/Express backend with MongoDB and JWT-secured APIs
Integration with Google Maps SDK, Firebase (APNS), Apple IAP, OAuth providers, and third-party data sources
User Roles
- Driver (App User): Receives alerts, tracks sessions, views reports, manages subscriptions, and submits camera locations
- Admin (Portal User): Manages users, monitors subscriptions, controls camera data, and moderates community submissions
