Cross-Platform GPS & BLE Integration

I need a developer who can quickly add reliable GPS tracking and Bluetooth Low Energy (BLE) scanning to my existing stack.

Here’s what I’m aiming for:
• GPS tracking on Android and iOS phones, implemented with Cordova or Capacitor so the same codebase serves both platforms.
• Continuous BLE scanning on Android, iOS, and the web to detect nearby beacons and surface their data in real time.
• Seamless wiring of those two features into my Next.js frontend and the current Node.js backend, with events flowing through clean, well-documented APIs.

I’m looking for someone who has already delivered similar cross-platform location solutions, understands the quirks of background services and permissions on both mobile OSs, and is comfortable debugging over the air.

Please respond with a concise but detailed project proposal that shows:
– a brief example of past GPS / BLE work,
– the tools or plugins you plan to use (e.g., specific Cordova/Capacitor packages),
– an outline of milestones leading to an end-to-end, functional prototype,
– your availability to start right away—I need the first workable build ASAP.

If this integration works smoothly, there’ll be follow-on work for refinements and new sensor features.
