Needed 2 raspberry developers

We are looking for 2 very experienced developers for Raspberry which can also work with "Relay" to manage things. We only need someone which is also available this weekend on saturday and sunday as well. We already have a Raspberry pi 3b with a relay and what we want is that this is connected with our server (our laravel team gonna help you with this). We just want a Open / Close signal on the "Relay" which is managed by the Raspberry PI which is connected with Internet to our server. Each Raspberry need to be uqinue id stored in our database because we need to know when it is offline etc. As 2nd we want to connect a RFID / Barcode scanner which also works together with our Laravel platform. (Our laravel team gonna help you with each step which you need from our side). Please translate this page with google translate: [login to view URL] I want that i don`t need to run anything on a PC I want that i just can go to a GYM and there i put power on the Raspberry i connect the RFID with USB on the Raspberry and i also connect the relay and it works. I don`t want only RFID i also want Barcode scanner but i think thats the same then? I need to ping on regular basis which each raspberry and when there is a error i want a error code back (our laravel team take that error_id to take action for example send a email to gym owner) our laravel team managed that. But we need to check for example each 15 minutes for the status for each raspberry Each raspberry has to be stored in a database (because each raspberry is unique) ofcourse because a lot of gym owners gonna call me hello can you send a machanic my raspberry is not working. I want to read a log then from that raspberry and there i can see OW oke the RFID is disconnected OR the power is gone or that kind of errors. We connect that Raspberry with Wi-fi to answer with our server
