Hello there,
If you are looking for expertise in the devices you have listed then you are rested assured that I can deliver the service of which you require. All you need do is to provide the details and requirements for the project or your intended application, list out the extent of work that has been done and what is to be done. If any work has been done, you can do well to describe tests that has been carried out on the work to enable me get up to speed with the work, else we would have to retest the work.
I have tinkered with the RPi 2 and 3 for surveillance application, for interfacing with arduino, etc. I am currently working on the gps module, and the GSM module I have tinkered especially in an application that involved interfacing with an LED Grid to display messages sent to the module to be displayed on the LED Grid. Also carried RFID interfacing with arduino for security access and control.
Do send the specification of these devices in your custody and message me so that we can discuss adequately the requirements to be met and see how well and fast we can deliver.
Regards,
Henry.
