[emoji106][emoji106][emoji106] on c4 for this use case you are describing. I’d hire a good c4 expert to help you through your design and get your core building blocks in place. C4 is really scalable, and rock solid reliable if designed by the right experts. Plus, because it is scalable, you will catch your self with use cases that you are not even thinking about now, but if you get the foundation right can be added when time is right.
