MQTT Jobs
MQTT is a Client Server Publish/Subscribe messaging transport protocol. It is lightweight, quick and efficient, which makes it useful for the Internet of Things (IoT) devices and low-powered networks. It enables a client to publish or receive data from a broker (server) with very little overhead. As such, an MQTT Developer is essential in making sure that the MQTT based systems remain operational properly and all the IoT devices are able to maintain effective communication.
Here's some projects that our expert MQTT Developers made real:
- Creating secure MQTT servers on VPS that allow for the transfer of data via API
- Developing example code for the ESP32-S3 development board to send and receive data with Quality of Service (QoS)
- Modifying python code to interact with various other applications using MQTT
- Designing custom firmware for microcontrollers such as STM32, TI CC3200, etc. that utilize MQTT protocol
- Providing custom solutions for low cost wireless spectrophotometers using MQTT
