Omni IoT communication API implementation

I am at the middle of creating public bicycle sharing project. Part of the app is done. The missing part is creating the communication API(Real-time GPS tracking, QR code / ID scanner integration, Smart lock) and backend management parts. This job is very ideal for someone who has experience in OMNI IoT. The TCP communication description is attached.
