Hi there!
You will be glad to know that, I have customised a BBB system last month. Currently, the system is running on EC2 instance with a TURN server.
I think, I can help you solve your issues.
I am new to this freelancer platform though,
However, I have over 6 years of experience in software development for local & global companies.
Thank you for reading this. Should we talk over a voice call perhaps?
