U-Track Lite

01

The Challenge

Deliver a reliable fleet tracking and telemetry application that handles continuous high-frequency GPS updates, heavy route map rendering, and flaky mobile network environments without battery or UI degradation.

02

Architecture & State Patterns

• Flutter architecture utilizing BLoC/Cubit for state isolation between map tracking, telemetry metrics, and vehicle list states.
• Repository pattern with SQLite local storage for offline-first telemetry caching.
• Modular map engine supporting both Google Maps and FlutterMap.

03

Backend, APIs & Platform Boundary

• Dio HTTP client configured with custom interceptors for authentication, token refreshing, and adaptive request throttling.
• Firebase Cloud Messaging (FCM) integration for real-time fleet alarms, route deviations, and geofence alerts.

04

Performance & Data Optimizations

• Achieved an approximate 40% load-time improvement through local SQLite persistence, data-processing optimizations, and adaptive polling.
• Engineered animated route polylines and custom vehicle map markers with smooth 60fps trip replays without frame drops.

05

Verified Outcomes & Production Delivery

• Personally engineered and published the complete application to Google Play.
• Surpassed 1,000+ Google Play downloads with active commercial fleet operations.
• Significant reduction in client bandwidth usage and faster cold-start app launch.
