iBeacons using MQTT protocol for tracking development

I am looking for a developer to work on a project that involves using iBeacons with MQTT protocol for tracking the location of objects in real-time. The data should be stored on a server or (possibley the cloud) then presented on a Web Portal.

The portal shall allow adding, removing, of gateways, beacons etc and showing the data stream.

Use of MQTT as the communication protocol is we need to communicate with the gateways.

Develop the program using open source broker such as Mosquitto, HiveMQ, and EMQ X, or the cloud-based MQTT brokers, such as AWS IoT Core, Azure IoT Hub, or Google Cloud IoT Core, which offer scalable and secure MQTT broker services.

The web application or any other client can then subscribe to the relevant topics on the broker to receive the messages in real-time. This can be done using a variety of programming languages and frameworks, such as Node.js or React.

Ideal skills and experience for this job include:
- Proficiency in BLE and MQTT protocols
- Experience with developing gateways and servers
- Knowledge of web development languages such as HTML, CSS, and JavaScript
- Ability to integrate different systems
- Strong problem-solving skills
- Ability to work in a team and communicate effectively.

Please provide a quote to complete and time needed.
