hi
we have excellent experience in build iot platforms
we don not use (ibm-iot) or firbase ,etc
we build it form scratch according client needs ,l like:
- is there embedded devices which will auto send data to the main server?
- will client need use http request or Mqtt tech?
- do client need monitoring on webpage or on desktop application , etc?
we always use :
- amazon cloud servers.
- MQTT(mosquitto) or http request.
- mysql or mongodb database
- nodejs , express for GUI web interface
- Qt/c++/QML for GUI Desktop interface
note:
we provide free demo before accepting bid
