Building a Hyper-Local Food Delivery App with Kotlin and Jetpack Compose

Food delivery apps generate $350B globally. We built LocalBite to connect home chefs directly with neighborhood customers.

1. Map-Driven Discovery

Using Google Maps SDK, nearby listings appear as interactive markers. Clustering prevents overlap in dense areas:

kotlin
@Composable
fun ChefMapScreen(chefs: List<Chef>) {
    GoogleMap(
        cameraPositionState = rememberCameraPositionState {
            position = CameraPosition.fromLatLngZoom(userLocation, 14f)
        }
    ) {
        chefs.forEach { chef ->
            Marker(state = MarkerState(position = chef.latLng),
                   title = chef.name, snippet = chef.specialty)
        }
    }
}

2. Real-Time Order Tracking

Firestore snapshot listeners push order status changes instantly to both chef and customer screens.

3. Native Payments

Stripe SDK handles Google Pay integration with PCI-compliant tokenization, ensuring no card data touches our servers.

Summary

Kotlin + Jetpack Compose delivers a smooth, native Android experience while Firebase handles the real-time backend complexity.
