React Native Uber-style Tracking App

I am building a driver application (React Native) and I need an experienced developer to implement a high-performance GPS tracking system similar to Uber.

Core Requirements:
Real-Time Driver Tracking
Smooth live location updates (no lag or jump)
Update frequency: 1–2 seconds
Accurate GPS (no drifting issues)
Polyline & Route Sync
Route (polyline) must update instantly with driver movement
No delay between driver marker and route line
Smooth animation (like Uber)
Dynamic Rerouting
If driver takes wrong turn → auto generate new route immediately
Detect deviation from route
Support U-turn detection
Turn-by-Turn Navigation
Voice instructions (left, right, U-turn)
Real-time direction updates
Map Performance Optimization
No lag while moving
Efficient API usage (Mapbox or Google Maps)
Background tracking support
Advanced Features (Important)
Speed detection (overspeed alert)
Harsh braking detection
Route snapping (match GPS to road)
