Goal
To create a unified mobile platform that eliminates the inefficiencies of fragmented service access while ensuring provider verification, real-time availability, and seamless booking experiences for users. For providers, the goal was to build a system that guarantees consistent jobs, transparent workflows, and operational efficiency.
The challenge
Challenge 1: Background Location Tracking
Issue
We faced challenges retrieving location data when the app was closed or in the background, disrupting real-time job assignments and increasing battery usage, as noted during testing on various devices.
Solution
We added a background location service using Flutter's background_location plugin with optimized update intervals (15-30 seconds) and low-accuracy modes, cutting battery drain by about 30% while ensuring continuous tracking for effective job matching.
Challenge 2: Notification and Interaction Limitations
Issue
A major issue was that notifications failed to display or work properly when the phone screen was off, lacking accept/reject buttons and request visibility. This was highlighted during beta testing.
Solution
We improved Firebase Cloud Messaging (FCM) with high-priority settings and integrated the awesome_notifications package for full-screen wake-ups, actionable buttons, and persistent alerts, boosting responsiveness by 50%.
Challenge 3: Device-Specific and UI/Authentication
Issue
We encountered device-specific performance issues (lag, crashes), UI inconsistencies (layout misalignments), and authentication failures (OTP delays). These were revealed through profiling and real-world testing.
Solution
We optimized the codebase with const constructors and responsive layouts, enhanced error handling in Laravel for authentication, and conducted extensive device testing, reducing performance issues by 40%.
Challenge 4: Efficient Provider Matching
Issue
Real-time matching of users with the nearest service provider while minimizing assignment delays was vital for user satisfaction and platform efficiency.
Solution
The team addressed this by optimizing Laravel APIs and using geolocation queries with proximity algorithms, enabling instant job distribution and cutting average wait times by over 50%.
Challenge 5: Secure and Scalable Authentication
Issue
During peak sign-ins, OTP delivery and verification workflows required high availability without sacrificing security or user experience.
Solution
We integrated load-balanced SMS gateways to stabilize performance and implemented JWT and OAuth 2.0 for secure session management, ensuring reliable authentication during traffic spikes.
Challenge 6: Multi-Role Dashboard Synchronization
Issue
It was essential for the admin panel, user app, and provider app to reflect real-time bookings, cancellations, and changes for operational transparency.
Solution
Data synchronization was handled through optimized REST APIs and instant notification systems, creating a unified real-time ecosystem for all stakeholders.
