Hi, glad to inform you that, I have already done this project several times for multiple clients, you can see my portfolio.
I have 10+ years of experience. I am solution architect in cloud platforms AWS, AZURE, Google Cloud, Digital ocean. I will provide you highly resilient solution with auto scaling, so that in case of high traffic system will be auto scaled to handle capacity and when load decreases system will automatically descale itself.
I have also configured JIBRI for recording and I can also provide authentication.
See my work at https://vchatapp.com.
Please discuss for further details.
Thank you!
