Indoor Navigation Mobile App Development With BLE

I'm looking to develop a mobile app for indoor navigation utilizing Bluetooth Low Energy (BLE) technology. This app should be compatible with both iOS and Android platforms with Source Code.

Key Features:
- Navigation: It should provide turn-by-turn directions, detect Points of Interest (POIs), and optimize routes.
- User Interaction: The app should include a user login/authentication system, work in offline mode, and provide real-time updates.

Ideal Skills:
- Proficiency in cross-platform mobile app development, ideally with experience in BLE technology.
- Strong understanding of navigation systems and route optimization.
- Capability to implement secure user authentication and real-time data syncing.

Experience:
- A portfolio showcasing similar projects will be highly regarded.
- Previous work on indoor navigation apps is a plus.
FEATURES like:

~ Indoor Map Navigation
~ Search for Locations/Points of Interest (POIs)
~ Route Guidance to Destination
~ Interactive Map Display
~ Multi-floor Navigation
~ Current Location Identification
~ Turn-by-Turn Directions
~ Nearby Amenities Information
~ Accessible Routes Highlighting
~ Favorites/Bookmarks for Locations
~ Feedback/Report System
~ Language Selection for Instructions
~ Real-time Updates on Path Status (e.g., Congestion, Closures)
~ Notifications...
