Dear client, welcome to freelancer platform. I have an LLC based in Miami. We have a lot of experience working with Nextion displays, we have even debugged some practical questions from library provided by manufacturer, and added some resources to library like xfloat, global variables, etc.
Please, contact me in the chat to know specific details about your project (technical requirements, budget, deadline, agree on work system, etc).
You can see some sample projects developed by us by reviewing our website at www.xbintech.com.
We have a lot of experience developing systems remotely, I have mostly worked in Upwork. We have used Nextion screens (and we are using them) in several projects such like CNC machines, control valves system, battery manager system, etc, integrating this display with Arduino, Android phones via Bluetooth shield, etc. Just take a look to our website, I can also provide you pictures and videos from previous jobs.
Kindly regards
